Virtual Shoplifting

This is when you load up a shopping cart on a website, then you don't finish check-out, and not pay for anything that you put in it, and log off.
I have noticed with one website (Amazon) it says items will remain in the cart for up to 90 days. Does this possibly mean that the last one (or however many items) could sit on a shelf in a warehouse, gathering dust, until the time runs out or you go back and pay for it ?
This could be like reserving yourself something until you can afford it, if its like one of those "must have" Christmas presents.
