MRM 10lbs Whey Protein $49.49 with Coupon Code
Best Price Nutrition has a 10% off coupon code for 10lb containers of MRM metabolic whey. This coupon code is MRMW2. 10lbs for under $50 is always a steal. I've never tried this protein powder, so I cannot vouch for the taste.
You can choose from 3 different protein flavors: chocolate, vanilla and strawberry whey protein.
The coupon code is MRMW2. Expires September 30th.
