I get 12.5% bleach in 2.5 gal jugs at the pool store for $7. The prices are so close that it depends on if I'm closer to one or the other. I do think you need to think for yourself. Everyone on here says to buy bleach at Walmart. So I did it without comparing the 2.5 gal jugs at my pool store. My wife had a cow. Now when I want to buy that expensive Taylor test kit because everyone says it's the best, she won't let me.
I'm surprised a lot of people say to not check your pool water with your pool store. They have a computer to analyze it! But then I really watched them do it and the instument is only analyzing the color results on the test strip of paper they used. That can't be acurate. Furthermore, everytime I went there (of course I was in panic mode) as soon as they got the results, they throw some chemicals at me and say "you need this and you need this and you need this . . ." It was a viscous cycle. Now I really don't know how acurate the pool store is, but I rely on experienced pool owners who aren't trying to sell you chemicals.
EDIT: buying bleach at walmart (6% @ $2.50/gal, right?) is still cheaper than 12.5% @ $7.00/2.5 gal. Can someone double-check that? What is is $5.20 vs. $7.00 for the same relative amount?
