I purchased a Sasha-sized shopping cart for myself last year. Boo fell in love with it, but I didn't want to give it up. Instead, I bought a second cart and gave it to her for Christmas, filled with groceries (mostly from Lovvbugg on eBay). I also found her a couple of miniature shopping baskets (in the dollar section at Target - such a bargain!), one containing plastic fruits and the other containing plastic vegetables. This means she has plenty of supplies for her Sashas to go grocery shopping.
