Foot care products for under $1 each

My husband often complains of foot pain when he has to be on his feet for long periods of time, so I'm always on the lookout for deals on insoles.  I just picked some up at Rite Aid because of a great deal they are running:

3 Profoot Foot Care products - on sale 3/$15
Used 3 $1 off manufacturer coupons found here, and used $1.50 in +Ups
Paid $11.10 after tax
Submitted the $10 Single Check Rebate when you buy 3 Profoot foot care products (offer #2) at riteaid.com
Final cost = $1.10 or $0.37 each!

Keep in mind that while the $10 rebate is valid now through 8/30, the 3/$15 sale ends on 7/30.
