Odd request for MD 20/20

Anyone seen any around? It's the brightly colored $3 malt beverage in a gas station that probably is covered in dust.

Their website says Walgreens carries it but I haven't seen them. I've looked all over, and I've encountered enough unpleasant fish-smelling gas stations to run to yall for help :)

This is for a goof; I really don't enjoy the stuff but I need it for Mad Dog Monday, you understand.

edit: i haven't been on reddit much lately and i forgot i even made this years ago lol... cheers for your help https://i.imgur.com/OhviSZM.jpeg
