The free part depends on just where you hitch your trailer…here in the high rent district Gillette Fusion is $5.49 and $5.99 – other places have it for $4.99.  Use the $3 Wags coupon from 5/3 rp and the $2 mfr coupon from the May P&G.  I have quite a few of the $2.50 RRs from the Irish Spring deal, so have been using those to plug the gap (along with a few Kit Kats).

You only have to use one Walgreens coupon for your transaction – the $3 will come off each can.
