Yes, you could add items to it and when ready to order just add it to the cart. I had several items in it, like filters, ready to order so I wouldn't have to look up the part numbers every time. Now I can't find my wish list.
I know the cart will empty after a certain time period. But, there was a wish list list that things had to be removed by the user. If you ordered an item from the wish list, the item still stayed in the wish list. It was a great feature for keeping up with consumables that you needed to order often. I guess it was an unknown feature. I would like to see return.
