I managed to find seven, broken or not, at local Walmarts. Some were fully reparable because it was just an undone 'snap'-type connection. Others are broken in the middle of bands (or elsewhere not at the joints).

We are planning to build our robot with the expectations that balls will both figuratively 'break' (that is, come unsnapped) and actually break during competition, and that these in general will not be repaired.
