Woolite and Spray 'n' Wash are on sale for 2/$5 at Walgreens this week. There is also a July EasySaver rebate (#30) for $2 on each, making them .50. To sweeten the deal further, use either this or this printable $1 Spray 'n' Wash coupon. You'll make a profit of .50 a bottle.
Note: The end price I've listed is purposely lower than the one in the ad flier. For some reason Walgreens combined two different rebate offers in one ad photo, confusing the final price. If you do the math on the deal, it still comes out correct.
