Code Rocket50 is valid on Woke AF and Bucked Up Rocket Pop flavors ONLY. Code expires 5/13/20. Free shipping on orders over $49.95. Doesn't appear to be a limit on how many can be ordered.
Also, another option if the above flavor doesn't work for you. Buy one bucked up pre-workout, get up to four additional cans for $39.95 ($10 savings). Mix and match flavors. (No code needed).
