I think most people here are more upset about the knowledge of a chain rather than their prices. I myself will always be looking for bargains which ultimately means I can't support the Mom and Pop store all the time, especially with big equipments such as filters. When it comes to buying fish, it goes to the Mom and Pop store, hands down. Tanks are something that you really have to look for. I find some deal are better at either places. The bigger the tank, the better the deals are at the Mom and Pops' and you can negotiate as well. Filters, heaters, food, decor, general equipment, etc. I have to give to the chain stores.
