^^ I agree with Krafty and KG. AD is 15 mins closer to me than Sarris is, but I still drive to Sarris for their service and personalbility (sp?) Sarris' prices are better from what I've seen so far, too! (usually as good or better than online prices after you factor in shipping!) Also, when I need something, I just call um up, have them order it, and pick it up when it comes in.
Keep in mind, this is just IMO and my POV (point of view).
I think AD would be a good store, but they're in a very high-traffic location, and from their POV, 70%+ of the people coming in are just there to see their tanks. So, why would you want to waste your time answering 1000 "What's this...?" questions per hour. I'm sure their location is good for attracting new people to the hobby, but, unfortunatly, this has just costed them some business of truly interrested hobbist as well.
