For products in a collection connected to the bundle variants, the product takes random items from the variant to show the price, displaying the lowest available price for that particular bundle.

A sample for this is an order that shows $72 on the collection page but the lowest price is actually $75.

The reason why you'll see $72 on the collection page is that there is a variant with that specific price for the bundle in question. This means it's correctly displaying the lowest available price for that particular bundle.
​

There could be various reasons why that order was priced at $72. It might be due to a previous discount applied either through Shopify or our app, or perhaps a different component price was in effect at that time. Unfortunately, we cannot pinpoint the exact cause.

1. Duplicate the bundle as a backup.
​

2. Go to the original bundle product.
​

3. Proceed to delete the $72 variants in the bundle product.
​

If this approach works, you can safely delete the backup bundle. If not, you can continue using the backup bundle, as it essentially serves as a duplicate.
