This Leslie's has been around FOR-E-VER. I'm not entirely sure how long, but ever since I can remember they've had this location, and I'm 28, so take that into account. I think they have prime location. Around a lot of older neighborhoods where every other house has a pool in the backyard. Not to mention these pools need maintenance.
I've dropped in here on a few occasions to get necessities for my pool. It's nothing really fun or cool, unless I pick up some floatie pool toys or something.
The customer service is pretty on par most of the time. Sometimes things seem a bit pricey, but there's only so many places you can buy pool supplies. The convenience factor for me usually wins out over price.
