Stacking opportunity: Muscle Milk's Manufacturer rebate codes program (Muscle Milk runs frequent rebate apps (Ibotta, Fetch, Checkout 51) layered on top of Costco / Sam's Club instant savings; the brand site offers a 10% off welcome code on first DTC order.) layers on top of this code. Apply the loyalty number first, then the promo code, then any active credit-card category bonus (most travel and grocery rewards cards code fitness nutrition as a 2-3% bonus category). On a representative $270 order, the stacked savings work out to roughly $95 versus list price.

The DealPulse comments thread on each coupon is the fastest place to confirm whether the code is still working for other readers.
