Store them in damp sand in a cool dark place. The damp sand (not too damp) will stop them from withering and the cool dark spot will stop them from sprouting for quite a while.

Yams are easy to grow - just save some from the fruit and vegetable depatment at the sumermarket. Cheaper that trying to get them from the sead supplier.
