For almost a year now I have been dealing with this store (Primarily the one on Dean Martin). Throughout my endeavors the staff has been kind and helpful. I have enjoyed very fair pricing and vast supply inventory. Last night a digital ballast failed. Having thrown out the receipt, I was in a bit of a panic. When I called, the gentleman told me to bring it down. When I did he tested my burnt out unit, went behind the counter and handed me a different one. That's it. No hassle. I mean that is what I wanted, but how often as consumers do we actually get it? I love this store. If you are interested in the hydroponics world, this is the best place to go. Thank you Advanced Gardens!
