As one of its daily deals, Amazon takes up to 40% off a selection of sports nutrition supplements. (Although the sale advertises up to 40% off, we found greater discounts within. Most prices are as marked, although a few items receive further discounts via clippable coupons.) Plus, most items are eligible for Subscribe & Save, which cuts an extra 5% off and bags free shipping. Deal ends today. A couple of best bets, with prices after all applicable discounts: Note: Be sure to cancel Subscribe & Save after your order ships to avoid being billed for subsequent shipments.
