If you haven't gotten enough free razors, head to Food Lion with THIS coupon and THIS coupon. (you can print each twice). YMMV as to whether you will be able to get overage, but I usually do.

If you don't have a Food Lion terribly close to you, or your Food Lion is out of these, don't forget that Wal-Mart and Target both price match with a printed ad in hand.
