Anyone have any ideas why my 12 pack mtn dew codes come up as invalid code for all 6 12 pk codes i have… thats 36 dam games, of course all my 20 oz codes worked

are the codes on the outside of the box?
if so i’d say someone took a picture of the codes and used them without actually buying the product

clever lil devils

offcours u guys over there in the states get stuff like that. i want x2 codes in holland!
