You can get some good deals on deodorant using coupons found here.
I love Dove Ultimate Go Fresh. Smells so yummy. My coupons are good one month from the day I printed them, so I'll wait to see if deodorant goes on sale before I use them. I check Target today and regular price is $3.64 (for Dove). I didn't check the men's deodorant because I'm sure my husband won't switch brands just because it's cheaper. :)
I saw this deal, and many other great deals, at one of my favorite sites, Saving with Shellie. Check it out!
