Four transactions in sets of two.  This is a great way to burn points.

1. Buy 3 Crest get a $6 RR ($11.97).  Use $2 coupons from January P&G ($5.97).  I paid with 5,000 points.  OOP was $1.81.  If you don’t have points, add a Christmas filler and the $2.25 RR from the second transaction for subsequent Crest transactions.
2. Buy 6 cans Glade aerosol for $8 and get a $2.25 RR.  Use the B3G1 Free coupon from 1/8 S (up to $1) or this B3G1 printable and the $6 RR from the first transaction.  OOP was 56¢  There is also a Checkout 51 offer of $1.25 when you buy 4.
