Everything above was free! Kraft Easy Mac was 2/$6, get $3 ECB when you purchase 2. Excedrin PM (and other types) 20 count is on sale for $1.99. I had two coupons for $2.50 from the 12/5/10 SS. Trident Vitality was $.99, get $.99 ECB.
My plan was to pay about $2.00 for all of the above because of the $.50 overage on each Excedrin PM. Awesome deal, because I like to have Easy Mac on hand when I need a fast meal for the kids. When I scanned my card, I got a $2.00 off Excedrin PM or Migraine CVS coupon (so buying two Excedrin PM made it a total of $3.02 money maker). I used $3.99 in ECB and got back $3.99 (plus $1 ECB for my fourth green bag tag). They had to adjust one of the coupons down by $.02, but I decided that I would rather do that than purchase something else.
P.S. To add a little nutrition to the Easy Mac, I add approximately a tablespoon of carrot puree (homemade or baby food). You could also try butternut squash puree but it has a stronger flavor so start out with less. To add antioxidants, use green tea for the water. The cheese covers the tea flavor very nicely.
For other scenarios and coupon match-ups, check out Simply CVS.
