Anyway, here is what I got:
At Publix, I spent $53.49 for $139.87 worth of groceries, a savings of 62%. My total should have been a little better than that, but the cashier didn't scan a couple of my coupons, which I didn't catch until I was home, and it wasn't worth going back for the sake of $4. (Granted, I had about a billion of them, but the way she did the coupons was very weird and confusing, and I will be sure to avoid her line in the future!)
At Winn-Dixie I spent $22.99 on $57.62 worth of groceries, a savings of 60%.
Overall, I spent $76.48 for $197.10 worth of groceries, an average savings of 61%. Combined with my Tuesday totals from Walgreens and Winn-Dixie (previous sale), this week I spent $111.23 on $356.19 worth of groceries, an average savings of 69% for the week.
