David must have walked into a different place because the prices are much better than Leslie's. When I first moved to the area I used Leslie's exclusively but after talking to my neighbors I learned of Sun Devil. My advice is go to both and compare not only prices but concentrations (muriatic acid isn't all the same). I also use www.troublefreepool.com as a pool owner website that teaches you how to properly care for your pool and I have found that Sun Devil is the most honest when it comes to what the forums tell you. Leslie's on the other hand will sell you algae one week and the algaecide the next if they could.
