For game play purposes, the Cans General Store located in of course The Cans of Mythburg. The owner/operator is a Goblin named “Olopeerak” whom is willing to negotiate prices. It has just about everything you'd find in the PHB's equipment section available for purchase at those same prices. There are however some additions/exceptions as noted here.

• 2 Canned Meals, which equal 1 day worth of rations. 5 silver.
• Can Opener, hand crank style, sturdy. 1 gold.
• Per local law there is no alcohol, nor alcohol related paraphernalia sold here.
• Costume Mask, full face covering. 3 gold.
  • Sold in 3 styles from this store, depicting a generic male face, generic female face, and a cat face. They're the sort of quality thing one might wear to be anonymous at a masquerade.
  • There has been an uptick in demand for these since Scry Cameras started appearing around the city of Mythburg.
