Thanks to bugsi033, I had 4 more $1 Benadryl coupons to use. I bought 4 boxes of Benadryl at RiteAid. They are on sale this week for 2 for $9 = $18 - $4 in Benadryl coupons - $12 in RiteAid Benadryl coupons = $2 and I'll get back $4 in rebates = $2 moneymaker!
I also picked up another bottle of Dawn detergent for $1 at A&P. I used my $1 coupon from the A&P coupon booklet, so it was free.
