This deal has ended.
Update: this has been extended through 6/30. New Drugstore.com customers can get a rare $5 off $30 or $10 off $50 via this link. Plus, get free shipping on orders over $25 and pay no sales tax (try that at your local store). Between the coupons, shipping and tax policies, pricing and other promotions (like a current buy 1 get 1 free on popular products), Drugstore.com can be a significant savings compared to your local pharmacy.
