Thats funny. Here is Michigan we have Meijer and Walmart that both sell fish. Luckily I live in the city and have 9 fish stores with in 20 minutes of me.
We dont have either off hem stores so here in a at australia why rite shocking to me. Sounds good in theory but from what you've said they don't seem to look after the fish all that well.
We have a new chain store called Pet Barn popping up everywhere which is pretty dodgy for fish and lots of independent stores but they seem to be closing down a lot these last few years. Would like to be able to buy my groceries and some fish at the same time though.
