Acme Mercantile is an odd shop located on the south side of Liberty between Main and Ashley.

Stepping into Acme Mercantile is like stepping into the world's smallest department store. They have more items than you thought could be squeezed into such a small space such as fake mustaches, unique clocks, flax clothing, toilet paper, bone-shaped paper clips, your favorite childhood candy, chilewich purses, and earth friendly cleaning products. Shopping at Acme can brighten even the worst day.
