How it works
How to design a bundle offer
Enter your item price and bundle size
Start with the per-item retail price and how many items are in the offer. The tool handles uniform bundles (same item x N) and lets you model different discount structures.
Pick the discount type
Percentage off the whole bundle is the simplest. BOGO works for even-numbered bundles. Buy X get Y is the most flexible - set how many they buy, how many they get, and how much off the 'get' items.
Check the margin before launching
The effective per-item price shows what you're really charging. Make sure it still covers your cost plus a reasonable margin. Deep bundle discounts can push you below break-even quickly. Use the markup calculator to double check.
Bundle offers that actually work
Bundles lift AOV when done right. When done wrong, they just discount what you'd have sold anyway.
Bundle complementary products
A razor and a year's worth of blades converts better than a 3-pack of identical razors. Complementary bundles increase perceived value and give a legitimate reason to buy more. Look at what customers frequently buy together (via your analytics) and build bundles around those pairs.
Headline the savings, not the discount
'Save $30' beats '15% off' for most audiences. Dollars are concrete. Percentages require math. Show both if you have room, but lead with the dollar amount at the top of the product page.
BOGO increases conversion more than % off
A 50% off BOGO promotion (effectively 25% off the average item) often outperforms a flat 25% off the same bundle. Shoppers love 'free' as an anchor more than numerical discounts. Same math, better story.
Set bundle quantity carefully
3-packs convert better than 2-packs for most consumable items. 5-packs hit a ceiling - shoppers worry about waste or storage. For non-consumables (apparel, accessories), 2-for-1 or matching-set bundles usually outperform larger bundles.
Don't discount the top seller
Use bundles to move slower-moving inventory or to introduce customers to secondary products. Discounting your best seller cannibalizes full-price sales. A bundle pairing your hero product with a lower-selling complement is usually the sweet spot.
Time-limit is a lever, not a default
A 'bundle price ends in 48 hours' creates urgency and converts better than an evergreen bundle. But don't run time-limited bundles permanently - shoppers catch on and lose trust. Rotate bundles quarterly, keep one evergreen for AOV.

FAQ
Questions, answered
A modest discount is usually enough for most ecommerce bundles. Deep bundle discounts often attract bargain hunters who won't convert at full price later. Small bundles with a token discount can lift AOV without training customers to wait for deals.
BOGO converts better for consumable products with short replenishment cycles. Percent off works better for one-time purchases where shoppers are evaluating a specific item's value. A/B test both on the same product for two weeks before committing.
BOGO is a specific case of Buy X Get Y (buy 1, get 1 free). The general form lets you specify different quantities and partial discounts. Buy 2 Get 1 at 50% off is a common variant that feels generous without giving away full items.
Match your store's general pricing style. If your single items end in .99, the bundle should too. If you use whole numbers for premium positioning, keep the bundle whole. Breaking the convention for bundles creates visual inconsistency.
Most platforms support auto-discounts triggered by cart contents. Shopify has it built in (Discount > Automatic). WooCommerce and BigCommerce require plugins. Automatic discounts convert better than code-based offers because they remove friction.
Show the bundle price next to the strike-through total, plus a small 'save $X' callout. Don't hide the individual item price - shoppers want to verify the math. Apps like ReConvert, Frequently Bought Together, or PickyStory handle the display out of the box.
Great bundles sell on reviews
A clever bundle gets attention. Real customer reviews for each item in the bundle close the sale. WiserReview collects and displays verified reviews on every product page.
