Instead I think this is a case of the online shopping cart being viewed too much like its real-world equivalent. Adding items to a cart online may be closer to bookmarking than to purchasing (another reason is to reveal the cost of items with hidden pricing, as is practiced on Amazon).
Even worse, some retailers (occasionally Amazon) require you to add something to your cart to see the sale price, which presumably they aren't allowed to "advertise."
I'd bet that very few of these lost sales are really lost sales. Either some other retailer got the customer's business or the customer decided not to purchase from anywhere.
In the end, adding items to a cart is no different than viewing an item's page (imagine the billions lost through "abandoned" page views!).
That said, it's still helpful. Permuto highlights the reasons behind cart abandonment. It's essentially a list stuff retailers should properly convey to their customers way before check out.
