I think the sale ends Tuesday but at least 2 of the stores I've been to are out so you could stop in & get a raincheck, then have time to get the coupons to make them free.
Select varieties of Right Guard Gel deodorant at Safeway are $1
Use $2/2 from here or here (print two from each location per computer)
PLUS go here and register your Safeway card for CouponLink, then add another $2/2 eCoupon
Get a raincheck for 10/$10 on Tuesday then using just one computer you can get 10 free (8 with printed coupons & 2 with an eCoupon on your card)
That's probably a year's worth of deodorant free in just a few minutes!
