We do and the baskets or tables offering a quasi-random assortment of items would be called Wühltische (wühlen - verb, to dig/borrow. Tisch - noun, table)

During easter you will find choclate, before New Year you will find fireworks, and during off-season you'll find random stuff there.

You need a new pair of headphones, check the Wühltische. That submersion-mixer you desperatedly want? It's somewhere over there.
