Anyone looking to increase their protein intake can save a good deal of cash today. Amazon's Deal of the Day offers up to 40% off a wide variety of protein shakes, powder, and more ways to fuel muscle growth. You can get deals on brands like Muscle Milk, Evolve, and more.
All of these deals are fine on their own, but many of them can be purchased using Subscribe & Save to get even bigger discounts. Once it ships, you can always cancel your subscription, locking in the savings as a one-time deal. Speaking of deals, these go away at midnight (assuming they don't sell out beforehand) so grab what you want before it's gone.
