I go every chance I get... Even if we pass a petsmart or petco, I still have to walk in and see if theres any winners :] Typically theres not but you never know! But my LFS has a $10 debit/credit card limit and I usually go and get a rat a week which is only like $4 so... I usually spend another $6 on some random food or fish I probably don't need :]
So much for saving.
