Winco worked OK but its a fair bit out of the way for me. Only 2 weeks on this and I'm already sick of buying 8+ jugs of bleach every week.
In DFW my Aldi has 8.25% 121oz jugs for 2.59. That's the best I've seen and beats Walmart by 11 cents/oz. I haven't checked dates, but I did just successfully SLAM my pool with it.
EDIT - Oh man I just saw the posts about Winco bleach. Will have to check that out. At $2 they beat Aldi by another 6 cents/oz
