Freakame, Freakayou!
As much as I <3 you Karen I have to side with this. You can also get Beta fishies there. The only fish on the planet that don't creep me out.
And those at WalMart tend to be quite hardy unless they're left in the hands of my sister. (Though my petsmart baby is a little over 2 years old).
I agree with Will on this. For those that need to be frugal, Walmart is great. As a company, they're not so hot.
