Percentages are the default currency of retail promotion: quick to approve, quick to communicate, quick to copy. Their weakness is rarely stated out loud. A percentage only means something if the customer knows the starting price. If they do not, a discount is not a saving, it is a promise they cannot check.
That is where bundles start. A bundle names the number that appears at the till, not the number subtracted from something unknown. Laurens Mauquoi, Chief Digital Officer of nexeye, puts it this way on the Reyo podcast 360 Marketing & CRM: "We do not use percentage discounts. We do not think it makes sense to say: you get 50 percent. With us there are always very clear promotions." nexeye runs the eyewear brand eyes + more and has used multi-buy offers instead of markdowns for years.
This guide covers the mechanics, when each fits, how German retailers use them and when a percentage discount is still the right tool. The market view draws on the newsletters of German online shops that Reyo captured in the four weeks from 28 September to 25 October 2026. We do not name the shops, this is about patterns, not senders. And the limit of our data is clear: we see what was sent, not how it performed.
Bundle, tier, gift: keeping the terms apart
The four mechanics get used interchangeably, but each answers a different question:
| Mechanic | Example | What it steers | What the customer calculates |
|---|---|---|---|
| X for Y | four items for the price of three | units per order | price per unit |
| Set or pack | two products at one fixed price | basket composition | pack price against single purchase |
| Gift with purchase | a free item above a basket value | basket value | the threshold, not the saving |
| Quantity tier | 15 percent from three items | units, but in percent | percent on an unknown base |
The decisive difference sits in the last column. The first three name a final price or a concrete item. The fourth names a percentage and inherits the problem bundles are meant to avoid.
Why a bundle adds up and "50 percent off the second item" does not
Take the classic mechanic: 50 percent off the second item. Convenient to calculate in the back office, a puzzle with several unknowns at the front. Which item counts as the second, the cheaper or the pricier one? If it is the pricier one, the discount applies to the higher price and the calculation flips. Mauquoi's verdict is dry: "Far too complicated."
A bundle inverts the logic. Instead of a markdown on an unclear base, it names a sum for a clear quantity. Four pairs of glasses for 300 euros is 75 euros per pair, a division anyone does in their head. Nobody needs the list price, because the comparison is not against your price sheet but against what the same quantity costs elsewhere.
That yields a test question for every promotion: can your customer work out the final price without a calculator and without knowing the original price? If not, you need explanatory copy, and explanatory copy costs conversion.
The model also has to be learned culturally. Mauquoi notes that in the Netherlands and Belgium practically every provider runs multi-pair offers, proven there over years before the model came to Germany. The question "why bundles in the first place?" he calls "a very German question." In a market trained on percentages, a bundle has to carry its own rationale.
The four mechanics in practice
X for Y. Four for three, three for two, two for one. You give up one item and get volume in return. It works hardest where several units of the same type are plausible: basics, underwear, personal care, consumables. The rule for the free item decides everything. "The cheapest item is free" is the standard wording, worth using verbatim because it triggers no follow-up question.
Set or pack. Several products at one fixed price that together cover a use case. The leverage is the composition, not the price: you take a decision off the customer's hands. A set is therefore the only bundle mechanic that works with no discount at all, as long as the combination makes sense on its own.
Gift with purchase. A free item above an order value. Strictly a threshold mechanic, related in effect: it lifts the basket without touching the price of the main product. You pay with the cost price of the gift instead of margin on your core range.
Quantity tier. A discount from three items, a deeper one from five. A bundle in structure, a markdown in communication. Useful for steering the basket by unit count rather than value, less useful when customers do not carry your prices in their heads.
Attaching the right mechanic to the right second item is covered in the guide to cross-selling in e-commerce. How deep a markdown should go is the subject of discount strategy for e-commerce.
The bundle as an acquisition mechanic
The underrated part: a bundle does not have to be tied to one person. The eyes + more promotion is explicitly shareable. Two people walk in together, take two pairs each and pay the bundle price between them. The price offer becomes an invitation.
"The bundle strategy is not just a pricing story, it is a marketing mechanism to win more customers," says Mauquoi. The arithmetic is simple: a shared promotion produces two customer relationships instead of one, and the second arrives at no media cost. In his experience one person drives the purchase and brings the second along, whose conversion runs higher because the choice is made together.
So test every multi-buy mechanic for shareability. A promotion limited to one account, one address or one person gives up its acquisition effect voluntarily. If your margin carries it, shareability is the cheapest new-customer measure you have.
What German retail actually shows
Now the inbox check. Roughly one captured email in seven uses a bundle, tier or gift mechanic, and just under half of all shops run at least one within four weeks. The distribution is lopsided: the gift with purchase makes up the large majority, the genuine multi-buy stays a fringe case. Only about one percent of all emails names an X-for-Y offer.
Four examples from the window:
- A fashion retailer ran a four-hour promotion on a Thursday evening: buy three, pay for two, cheapest item free, limited to one collection.
- A second fashion retailer ran the same mechanic that evening across its whole range, already reduced items included.
- An optician offered three pairs of glasses at a fixed 150 euros, tied to an online appointment booking before the promotion closed and capped per location.
- A supplements brand sold a three-month supply as a pack and added a choice of gift above a spend threshold.
How to read it: the two fashion retailers show how tightly this mechanic clusters once it is in the market: two shops, same mechanic, same evening, different scope. The optician shows a bundle as an appointment engine. The fixed price sells a visit, not just volume, and the cap per location does the job a countdown usually does.
Second reading: percentages remain the norm
About half of all captured emails carry a price reduction, and where a percentage appears, it is a "bis zu" figure (up to) in a good four cases out of ten. The median fixed discount sits at 20 percent. The most common form of offer is a percentage, and the most common percentage is a ceiling that does not cover the whole range.
That is the gap a bundle works into. "Up to 50 percent" asks for two assumptions: that the markdown covers the product they want, and that the starting price is real. A fixed price asks for neither.
Third reading: the gift with purchase is the quiet majority
Around one email in ten works with a free item or service, across more than 150 shops. Where a threshold is named, the median sits at 85 euros order value. One beauty retailer added a skincare box above 250 euros, another an accessory above 69 euros but only within one product line. An online pharmacy added a drink above 49 euros, on non-prescription orders.
How to read it: the gift with purchase is the compromise the market actually runs. It lifts the basket, leaves the main product's price untouched and needs no explanation. What stands out is how narrowly it gets scoped: one product line, one order type, one device. That makes it a steering tool for a range rather than a general present.
Where these mechanics sit in the wider toolkit is sorted out in the guide to sales promotion in e-commerce.
When percentages are still right
Bundles are not a doctrine. A percentage discount is the better tool when you are buying volume and price itself is the product promise. Mauquoi makes exactly that exception in his own business: for a newly added consumable range he calls it a "pricing and volume game" and uses temporary percentage discounts at launch, aiming to become price leader.
The distinction transfers:
- Percentages, when the product is bought often, is comparable and price dominates the decision. The number is then a positioning signal, not an arithmetic task.
- Bundles, when the product is bought rarely, the list price is unknown and you need volume or visits. The fixed price is then the only legible argument.
There is a timing argument on top. On dates when everyone speaks in percentages, percentage communication costs margin without buying attention. Mauquoi runs a strong five-pair offer every Black Friday, which by his account around 80 percent of customers share. The dates for this quarter are collected in the Q4 guide 2026.
How to build a bundle offer
- Name the use case, not the quantity. Three pairs of glasses is no argument, everyday plus office plus sun is.
- Communicate a final price, not a markdown. The number you publish is the sum at the till.
- Fix the free-item rule in writing. "The cheapest item is free", in the subject line and in the terms.
- Decide on shareability. Can two people split the offer? If yes, say so explicitly, otherwise nobody uses it.
- Calculate margin on the mix, not the unit. Contribution per order is what matters.
- Place it against the market. If everyone in your window gives percentages, a fixed price stands out.
Common mistakes
- Anchoring a markdown to an unknown price. "50 percent off the second item" is a riddle, not a number.
- Translating the bundle back into a percentage. Turning "four for three" into "save 25 percent" throws away the mechanic's only advantage.
- Leaving the free-item rule open. Ambiguity ends up in customer service or an abandoned basket.
- Excluding bundles in the small print. If your promotional discounts do not apply to bundles, two mechanics work against each other. Pick one per campaign.
- Giving up shareability. A limit of one per order is convenient and costs the acquisition effect.
- Picking gifts with no link to the range. That buys a one-off take-up, not a repeat.
How Reyo helps
Whether a fixed price registers is decided by your customers' inbox that week, not by your offer. That half is what Reyo supplies:
- Competitor monitoring shows which shops run multi-buy mechanics, sets and gifts, with which thresholds, conditions and exclusions.
- The campaign planner puts your bundle window next to market dates, so your fixed price does not land in the week half the market goes to 30 percent off.
- Marketing recommendations condense market movement into concrete next steps for the current week.
Conclusion
A bundle is not a discount in disguise, it is a different way of talking about price: a sum instead of a subtraction, no price list required. In German retail that is surprisingly rare. Percentages remain the norm, often as an "up to" figure, and the genuine multi-buy shows up in about one percent of emails.
That is the opening. A clear fixed price for a clear quantity stands alone in a week full of percentage signs, and a shareable offer wins a second customer relationship from the same promotion. Percentages stay right where price is the product promise. Everywhere else, ask whether a sum would be the better number.
