Box Top Special through Sunday

From Rebeccah Boyd:

Here is the flyer from Winn Dixie this week 9/12 - 9/18.  If you buy 20 things with box tops on them (using your Winn Dixie card) you get 170 box tops instantly.  They will print these out for you at time of checkout.  If you go and buy another 10 box tops in the same week, you get another 70 box tops.  In other words, you get $17 for buying the things you normally buy, and if you go back, you get another $7.  Go Winn Dixie!
