The fastest way to ruin a good bundle is to price it by feel. A discount that sounds harmless at the order level can quietly erase the margin on your lowest-margin component. Pricing a bundle well takes ten minutes of math, and it is math worth doing before launch, not after the quarter closes.

Start From Blended Margin, Not Sticker Price

Add up the landed cost of every item in the bundle and compute the blended margin at full price. Your discount budget is the gap between that margin and the minimum you are willing to accept. A bundle of high-margin accessories can carry 20%; a bundle anchored by a thin-margin hero product may only afford 8%.

Price the Outcome, Not the Parts

Customers judge a bundle against the effort of assembling it themselves, not just the summed price. Curation, compatibility, and a single decision have real value, which is why a well-framed bundle converts at a modest discount. If your bundle only works at 30% off, the problem is the composition, not the price.

A Simple Discount Ladder

• Complementary bundles: 10 to 15 percent off the summed price

• Quantity bundles of the same item: 5 to 10 percent per added unit, capped

• Gift sets: minimal discount; convenience carries the offer

• Clearance bundles: whatever moves the stock, but label them as such

Show the Saving Clearly

Display the compare-at total next to the bundle price so the saving is legible at a glance. A real number beats a percentage for larger carts: saving 24 euros reads as concrete, while 12% requires arithmetic. Whichever you choose, keep it consistent across the store.

Test Before You Commit

Run the bundle at two price points a few weeks apart and compare units, revenue, and contribution margin, not just conversion. The cheaper price almost always wins on conversion and often loses on profit. Let contribution per hundred visitors make the call, and revisit the math whenever your costs change.
