Price is not really the issue here.There's nothing wrong with cheap tubers. Just try to choose the plumpest ones ( not dry shrivelled ones) and hope that they have growth "eyes",which are the points from which the shoots emerge. You can sometimes see them ( little buds in the joints of the tuber/stems.) Sometimes they are there but you can't see them because they are beneath the surface, and will appear later. If there are no eyes , no matter how plump is the tuber, they might as well go on the compost heap. Even expensive tubers can be eyeless.
