Just a quick note
To add on to everything everyone else has said, yes generally speaking chain stores are cheaper, however, if you stop at a mom and pop store just to check it out, they want you to come back. This means that they will try to find out what youre looking for and will try and make you happy. Of course, chain stores want you to come back too but the customer service is usually pretty skimpy. At my LFS, we are really good friends with the owners, we've only been going there for about 3 months and they are some of the nicest people we've met. And their fish and equipment is more expensive than a chain store, but they are able to give "deals" if they see fit. Like I said, we've been going there for a while and since they know us and know that we will come back, they cut us deals on supplies and fish whereas in chain stores the marked price is just that and its not changing. Also, we give them mollies and they give us store credit. This pays for any fish supplies we need so now not only are we, the customers happy, but the owner is also happy because he is getting fish that have not traveled far in a plastic bag, they are from teh same type of water, and they were not bred in a giant vat in the middle of some fish farm. Also, many chain store employees are not as knowledgeable as many LFSs.
