Fruity Pebbles says leave the wallets at home, because they’ll take actual pebbles for free boxes of cereal.

The Pebbles Pay Tour will hit up Walmarts across the country like Rock Hill, South Carolina; Little Rock, Arkansas and Round Rock Texas this month, offering up free boxes Fruity or Cocoa Pebbles to those who pay with pebbles, stones or rocks.

Fruity Pebbles is asking that you leave the boulders at home, though, and just pay with a handful of rocks, which will be donated to local parks.
