My users have two problems and I'm hoping somebody else has had these already and there is a fix for it.
First of all the site caters to purchasing and downloading ebooks. No physical products.
1) A user may add more than 1 book to their cart but the cart only shows 1 book. When they go to pay the amount is correct and they receive confirmation that all of their books were ordered. Er, WTF?
2) Multiple formats are available for download after purchasing a book (five of them). However there is nothing to differentiate between these links. I have not had a chance to recreate this issue myself yet, but I'm wondering if there's an easy way to resolve this (e.g. changing the product name or something)?
