I see people referring to Leslies on the Forum. I'm surmising it's a pool supply store. Is it a local thing?

I'm out of CYA reagent and have been waiting on Ben's reorder for several weeks now. I tried finding Taylor reagents at our two local stores but they have what I term "kiddie" kits and looked at me strangely when I asked about Taylor. Is Leslie's on the net?
