I hit the jackpot at Walgreens today! I should disclaim that I have made multiple separate trips to two different Walgreens stores in the area. These were not all done on one transaction, but I have totaled my receipts here as though it were just one order. Today I bought:
four Gum Eez-Thru flossers (1 90 ct. and three 90 ct + 20% more bonus for 110 ct.) @ 2.25 each
four 4 ounce tubes of Crest 3D Vivid white toothpaste @ 2.99 each
four packs of Scunci hair elastics @ 1.99 each
two Oral B Indicator toothbrushes @ 2.25 each
four cans of Nivea for Men shave gel @ 2.99 each
three boxes of Robitussin 2 Go @ 2.49 each
a bottle of Secret body spray in lavender @ 3.49
a tube of Gillette Pro skincare @ 5.49
two boxes of Advil PM @ .99 each
three 1 count boxes of ThermaCare @ 2.49
one Walgreens vanilla caramel candy @ $.33
and a 2-liter bottle of Hawaiian Punch @ .99
and not pictured is 1 Gum flosser, 1 Thermacare, one Advil PM, 1 Scunci hair elastic and 1 Robitussin 2 Go.
Before the sale prices my total was $114.85.

After using $10 in Register Rewards and two $1 off Crest coupons, my out of pocket total was $21.89.
I received a total of $27.74 back in Register Rewards for a profit of $5.85.
