I was at Walgreens the other night and saw that Headblade replacement blades were $6.99 on sale through the 26th. If you have a handful of coupons from Headblade, that's $5.99 each.
If you need other headblade products, use the links on this site for a 20% discount, but this Walgreen's discount is a lot better than 20% and there is no shipping charge, but there may be sales tax.
The Headblade sport was $9.99, but most of you probably have that already. The Headslick was also $6.99.
