I used this $1 Spam set I got from Target awhile ago as additional market food.
I found this mini chrome shopping cart for $9.99 at World Market. It is similar to a 1940's shopping cart someone might have used in Pono's Market. I added the food from the Wal-Mart food basket. The pineapple and other fruit say Hawaii to me. For $18.99 for the two sets, this would make a fun gift set.
The wheels spin easily on the metal cart.
