Question about bleach prices, this is my first year with my pool, so I've never really paid much attention to bleach prices. My local Sam's club sells 3 bottles (121 oz bottles) of 8.25% HE bleach for $8.50. Is this a fairly good price? Also, my local pool store sells 5 gallon containers of liquid chlorine, 12%, for $14.78, but I have to put a $7 deposit down on the container. I guess the liquid chlorine would be the better deal, but I'm going to have to run back and forth to the pool store pretty frequently to get it filled up, which is about a 30 minute ride each way. I guess it'd probably be worth it to just throw down the $21 deposit and grab 3 containers so I can keep 15 gallons on hand and go get them refilled as needed?
