Go here and print a coupon for $6.00 off any 2 Schick Disposable Razors (excluding 2 count). This is an extremely high value coupon and will not last long.
Wal-Mart sells Schick Disposable razors for as low as $1.97 for a 10 pack.
You could pick up two packages and get them both FREE with an additional $2.00 overage to help cover other items on your grocery list.
Note, on the bottom of the coupon it states no cash back if coupon exceeds retail price. Wal-Mart's policy is to give the customer overage, so I am not sure how Wal-Mart will handle this. At the very least, you should be able to pick up razors for FREE!
