I just was able to order 1 Zhu Zhu hamster online through Walmart.com  head over there and search for them.  I put a 2 pk of them in my cart and it gave the option to buy just one at the top in the other customers bought section.  I added one of them to the cart got rid of the 2pk because we only really need 1 and am getting it shipped to my home.  They are only $8 at Walmart but act fast they may be gone soon.
