Even PewDiePie has to get the shopping done, why is that so weird?
Play as PewDiePie and make the most money you can but be careful not to pick up the wrong items at the store as it will negatively impact the money you make.
Fill PewDiePie's trolley with items that get the highest score!

Buy hats to customise Pewds with the money you make from the store (that's how shopping works, right?)
