Southern Cali Saver is reporting that the following Walgreens Kotex deal is rolling. This means that you can use the register reward you receive from buying Kotex to purchase another transaction of Kotex and reduce you out of pocket costs to $0 + tax. A Register Reward will then still print making for an endless number of free Kotex transaction (assuming you have coupons).
I can't guarantee this is still working, but it might be worth a try. Just note that they generally stop these "rolling" offers quickly so it could end at any point. Let us know if you try it!
