Query: Cart is wonderful but beware of shipper

The cart is one of the most useful items I have ever owned. So useful in fact, that I wanted to give two as Christmas gifts. I placed my order with Stacks & Stacks (Amazon's distributor for this item) on Dec 2. On Dec 19, I called and talked to customer service, my order is still unshipped. So before you order this handy little cart, make sure you don't mind waiting a LONG time to receive it.
