Call your local Bath and Body Works store before you try this deal and check to make sure that their antibacterial soaps are on sale 4/$10. Rumor has it the sale is ending after today (Sunday the 16th), but it may have switched over already.
Then click and use THIS $10/$30 coupon. If you buy 12 soaps that's $30 minus the $10 coupon. $20 for 12 soaps makes them $1.67 each (plus tax), which is better than the 5/$10 sale I usually hold out for. This is only in stores.
Again, make sure you call your store and check on the price of the soaps before you make the trip.
