Where can I find cool Gir or Domo shirts? Other than Hot topic?

I would like to order Gir, Domo, and Pacman shirts, but at reasonable prices. Hot Topic charges too much money. I want to buy at least 3 shirts and 3 accessories while only using $40 or less. Im a size youth medium and a XS (junior). Any suggestions?? I need answers ASAP!!!!! Thank you.
