I'm on my 3rd house right now (have had a pool at each house), but this is the first time I've adopted the TFPC strategies. I joined this site maybe a couple of years ago - I must have had some questions, but only recently did I really read the links and actually attempt to learn the techniques here.
It's a strange, but liberating feeling that I pretty much don't need to ever set foot in a pool store. Until now, I always felt dependent on the pool stores, and always was a little nervous that they were overcharging me, and I know I sometimes got bad advice, and I always had to learn whom to trust more, and whom to trust less.
I'm still not quite used to the feeling of staying out of those stores, but I like it.
