Now this is a really good coupon and one you almost never see! You can get a $1/1 Arrid coupon right now. Now Arrid is .99 almost every week at one store or another- so basically free after coupon.
At Walgreens it is .99, use the in ad coupon and get it free (give the manufacturer coupon first though).
At Rite Aid it is $1.50 this week- so .50 after coupon. (in the past Rite Aid has had double packs so you might keep an eye out for those.)
These are also priced at $1.00 this week at Safeway so free after coupon!
AND if those stores are not convenient for you, you can always take the Walgreens or Safeway ad to Walmart or Target for a price match.
