Amazon has a new 20% coupon for BSN SYNTHA-6 Protein Powder, Strawberry Milkshake, 5lb
Combine it with Subscribe & Save option to get another 5% off and free shipping.
The final price is $32.80 (or, if you have 5+ subscriptions this month, $28.43)
Coupon works on other flavors as well.
Note: this is a new coupon. I got the same deal on Black Friday - today it re-appeared again, allowing me to order another jar.
