How do I price bundles?

The habit is to take a round discount off the combined price and move on. That is how bundles quietly lose money. The right starting point is the gross profit on each item in the set, because that is what the saving comes out of.

Add up the cost of goods for the items in the bundle. Add up the prices. The difference is the pool you are working with. Now decide how much of that pool you are willing to give away in exchange for a larger, simpler order.

A useful rule is that the bundle should earn more gross profit per order than the single item it replaces, even after the saving. If your typical order today is one item, and the bundle earns less profit than that single sale did, you have made your business smaller in exchange for a nicer looking average order value.

The other input is what the bundle saves you operationally. One order instead of two means one pick, one pack, one delivery cost and one payment fee. Those savings are real and they can fund part of the discount, so count them before deciding the price.

A saving should be doing a specific job. Name the job first and the number becomes much easier.

If the job is to get a first time buyer to try more of the range, the saving needs to be visible but small, and the bundle should include your best introduction to the brand rather than your slowest moving stock.

If the job is to raise average order value on a store where most people buy one thing, the bundle needs to be the natural second item, and the saving only has to beat the effort of adding it separately. That is usually a modest amount.

If the job is to clear stock, the saving can be larger, but then it is a clearance offer and it should be temporary and labelled as such, otherwise it resets what customers think your prices are.

If the job is to shorten the reorder cycle on a consumable, the right structure is quantity rather than variety, and the saving should be expressed per unit so the value is obvious.

Bundles that fail usually fail because nobody decided which of those four they were.

The fixed set is a curated group sold as one product, at one price, with its own page. Price it against the sum of the parts and show both numbers. This shape suits gifting, starter kits and anything where the customer would not know which combination to choose. Because it has its own page it can rank in search and run in Shopping ads, which makes it the most useful shape for acquisition.

The build your own bundle lets the customer pick a number of items and applies a saving when they hit the count. Price this per item rather than per set, so the maths is obvious at any size. It suits categories with variety and personal taste, like flavours, scents and sizes. The risk is margin drift, because customers naturally pick the most expensive eligible items, so either flatten pricing within the eligible pool or set the saving from the cheapest item in the range.

The quantity pack is the same product in multiples, priced with a per unit saving that grows with the size. It is the simplest to run and the easiest to explain, and for consumables it does more for repeat purchases than any variety bundle, because it moves the customer's next reorder date further out and makes it yours.

The bundle price only persuades if the comparison is easy. State the total price of the items bought separately, the bundle price, and the saving as a single figure in currency rather than only as a percentage. People check money faster than they check percentages.

List what is in the set with the individual price beside each item. This does two things: it proves the maths and it introduces products the customer may not have known you sold, which matters for the next order.

For quantity packs, show the per unit price. A shopper comparing pack sizes is doing per unit arithmetic in their head, and doing it for them removes the friction.

Make the bundle its own product page with its own photography and its own description. A bundle that exists only as a cart rule cannot rank, cannot be advertised and cannot be linked to from an email. Give it a proper name and treat it as a product.

Avoid stacking bundle savings with sitewide codes unless you have deliberately decided to. Excluding bundles from generic discount codes protects the margin you priced.

The measurements that matter are gross profit per order and the effect on the products inside the bundle. Average order value on its own will rise almost automatically and tells you very little.

So track four things for the eight weeks after launch. Gross profit per order across the whole store. Unit sales of each item in the bundle, both inside and outside the set. Total orders, in case the bundle is confusing the choice and slowing people down. And return rate on bundles compared with singles.

Cannibalisation is the number to watch hardest. If bundle sales rose by a hundred and single sales of the same items fell by ninety, you gave a discount to customers who were already buying. That is a real risk with generous savings on your bestsellers, and it is why the bundle usually works better when it pairs a strong seller with something people would not have added on their own.

Review the price twice a year. Costs move, and a bundle priced against last year's cost of goods can slide from profitable to break even without anyone noticing.
