Why the 'Buy it now' button disappears on a bundle

Stores that installed Bundlex Bundles after 31 October 2026 have Buy it now on bundles turned on from the start. Buy it now, Shop Pay, Apple Pay and the other express buttons stay on bundle offers and send every item to checkout at the bundle price, free gifts included. The buttons still hide while a subscription is selected.

Stores that installed Bundlex Bundles before that date keep these buttons hidden on bundles with different sizes, colours or a free gift. Some themes change the product form after our widget fills it, and then a customer could get the wrong items at checkout. If you want Buy it now on your bundles, contact us. We test it on your theme first and turn it on once every item and the price come through right.

Why older stores have it hidden

Buy it now skips the cart. It reads the product form on your page and goes straight to checkout. A bundle with different sizes or colours, a free gift, or an extra product needs more than one item in that form.

Shopify now lets Buy it now carry extra items, and Bundlex Bundles can pass the whole bundle through it. Whether that is safe depends on your theme. Some themes change the product form after Bundlex Bundles fills it, for example by switching the size late or resetting the quantity. Other apps can also take over the button. On those stores, Buy it now could send the wrong sizes or fewer items to checkout.

So on stores where Buy it now on bundles is not turned on, the button hides when a selection has more than one item, and stays for single-variant offers.

When Bundlex Bundles hides it

It hides in the cases below. The first two apply only when Buy it now on bundles is not turned on for your store. The last two apply to every store.

• The selected offer contains multiple variants, such as different sizes or colours.
• The selection adds extra lines, such as bundle products, gifts, or selected upsells.
• A subscription selection requires the supported add-to-cart flow. This includes a selling plan picked in another app's subscription control while the Bundlex Bundles subscription option is on the page.
• Selected products in add-ons-only mode need to be included with the main purchase.

For a compatible single-variant purchase without those conditions, Bundlex Bundles keeps the button visible and synchronized with the selected variant. Theme and payment-button availability still apply.

Turn on Buy it now for bundles

If your store installed Bundlex Bundles before 31 October 2026, contact Bundlex support with your store URL and a product page that has a bundle. We test it on your theme first: for each kind of offer on your store, we open checkout through Buy it now and check every item, quantity, and price. If the test passes, we switch it on and let you know.

When it is on, Buy it now sends the whole bundle to checkout with the discount, including other sizes and colours, extra products, free gifts, and selected add-ons. It still stays hidden for subscription selections, products ticked in add-ons-only mode, and a Buy it now button outside the product form, such as in a sticky bar or quick view.

If the test does not pass on your theme, the button stays hidden. You can still send shoppers straight to checkout: open your discount in Bundlex Bundles, go to the Advanced tab, and tick Skip cart and go to checkout.

If the Add to cart button itself is not working, see add-to-cart troubleshooting.
