I get my back up a bit when people talk about reducing shopping cart abandonment like its somehow this lost revenue. It's not lost revenue until you get a sale and the customer returns it. Until then, you are just speculating.<p>There's too much focus on the real-world customer where they somehow abandon a full grocery cart and leaving the store. This doesn't fully correlate on the Internet.<p>People abandon shopping carts all the time:<p>- they get disconnected from the internet.<p>- their browser crashes.<p>- Windows/OSX decides it needs to restart after an update.<p>And sometimes people, me included, just like to store stuff in a shopping cart as a way to "favorite" items while I'm browsing a site like Amazon. It's like bookmarking a product, without committing it to a Wishlist page (like on Amazon).
