She has a couple of other items, but I'm not sure if anyone would be interested in them: one is a plastic keychain, another is a travel mug with guinea pigs on it. They're not quite the same quality as the magnets, but they're still kinda cute. Let me know if you'd like for me to add them as well.
codyNpatches -- as far as selling via Amazon.com goes, I'd be happy to explain it if you want to PM me. ;)

Edit: Found it! I clicked on the guinea pig treat link and found what I was looking for!
