Don't you wish your customers could save items in their cart for later without having to go through the hassle of creating an account and making a list? Well... now you can!
Closely related to wish lists, the Save For Later feature allows customers to save items for later. The key difference however is that with this feature there is a handy 'Saved For Later' section on the shopping cart page that will display these items to customers before they go to checkout. The Saved For Later list can be thought of as a intermediate area between a temporary list and a saved wish list. It is the default list for saving items, and it is saved to a user's account if they are logged in. (This feature is still applicable for logged out users, although nothing will save to an account. It will just be saved to their current session)
