The bundle maths that stops your best products becoming the cheapest option

You have a £29 workbook, a £59 workshop and a £99 coaching call. Someone asks whether they can buy all three together, so you add them to one bundle and knock the price down to £99. The arithmetic looks tidy: £187 separately, £99 together. But you have also made the coaching call appear to be worth £11, the workshop £0, or the whole package less serious than any of its parts.

Begin with the prices you need to protect

List every item and its standalone price before you name the bundle. This gives each product a visible job in the offer. A buyer who only needs the workbook should still have a sensible way to buy the workbook. A buyer who needs personal feedback should be able to see why the coaching call costs more than a download. Without those reference points, your bundle becomes the only price people can evaluate.

The last row is not automatically the correct bundle price. It is the anchor from which you can explain the saving. If the combined offer costs £149, the saving is £38, or about 20% of £187. If it costs £129, the saving is £58, or about 31%. Writing down both numbers stops you describing a small saving as generous or a large saving as harmless.

Price the change in buying behaviour

A bundle earns its discount by reducing friction. The customer may otherwise need to choose the right order, remember to come back for the next product, or work out how the pieces fit together. Your combined offer can solve those problems by giving them one path. That is different from saying every item has suddenly become less valuable.

1. 1Write the standalone total: product A plus product B plus product C.
2. 2Choose the customer behaviour you want the bundle to create, such as buying the full sequence in one transaction.
3. 3Set a discount that rewards that behaviour without making the highest-value item look disposable.
4. 4Check the bundle against the most likely alternative, which may be buying only one item rather than buying everything separately.
5. 5Describe what is included, who it is for and what order to use it in.

That fourth check matters. In the example above, a £149 bundle is £50 more than the £99 coaching call. A buyer who mainly wants individual advice is not comparing £149 with £187; they are deciding whether the extra £50 is worth the workbook and workshop. Your sales page should make that extra decision concrete: preparation before the call, a shared method during the workshop, or a useful follow-up afterwards.

Do not discount time as if it were a file

Digital products can often be sold repeatedly without another delivery appointment. A coaching call has a fixed slot and a direct limit on your calendar. Treating both as identical units in a percentage discount can create a problem: the bundle sells more calls than you can comfortably deliver, or it trains buyers to wait for the combined offer.

Use structure instead of a deeper discount

If the maths says the bundle needs to be uncomfortably cheap, change the offer before changing the price. You might make the workshop the core product, include the workbook as preparation and offer the coaching call as an optional upgrade. Or you might keep all three at £149 but add a clear sequence: read, attend, apply. The buyer is then paying for a route through the material, not just a pile of files.

You can also use different bundle levels. A self-serve bundle might combine the workbook and workshop. A supported bundle might add the call at its full or lightly reduced price. This keeps the lower-priced entry point available while making the extra access visible. On store.fan, you can sell digital products from your own storefront; paid plans also add tools such as discount codes and flash campaigns through discount features. The tool can present the choice, but it cannot decide whether the choice makes commercial sense.

Check the numbers after fees and fulfilment

Your displayed discount is not the same as your take-home amount. Store.fan takes 0% of sales, while Stripe’s own processing fee still applies, so include that processing cost in your calculation. Also include anything you must do after purchase: reviewing an intake form, sending personal feedback, hosting a call or answering support questions.

For example, if the bundle adds a call, calculate the number of calls you can actually fulfil in the period you are selling it. If you can deliver ten calls and the bundle promises one to every buyer, ten bundle sales may be the operational limit. That is not a reason to invent scarcity; it is a reason to state the delivery arrangement clearly or make the call an upgrade.

Make the saving easy to understand

Show the standalone prices, the bundle price and the difference. Then explain the sequence in one short paragraph. “Buy separately: £187. Bundle: £149. Save £38. Use the workbook first, attend the workshop next, then book your call.” This gives the buyer three checks: the arithmetic, the contents and the intended result.
