There are currently 3 shops in the game: the Mechanics (Annica and Nora), the Pawn Shop (Alexa), and the Chud King. The Chud King's shop opens up after you make the chuds happy enough and have the arcade unlocked.
Oh, was confused because I didn't realize I had to click on the buy option again! I feel a little stupid now. Thanks for the response and the help!
