I went tonight and got the last 6 cans (they're the smaller cans, BTW), and had no problem using my coupons. The mgr told the cashier to "force them thru", and hit "mfr cpn" for each one.
BUT, don't worry about it if your store won't take them. WM has them in the trial sizes (same size as the one on sale at Eckerd) for 97¢. I ended up using the rest of my cpns there

. Coupons expire Sat., so hurry!
