As we are all familiar with by now, ProPlan has changed the formula on most of their adult foods so we have decided to stop feeding it.

We had fourteen of the ProPlan "$7-off per bag" checks to use, but scoured all the PetCos in the area and found the last seven bags of the old formula. That leaves us with seven "$7-off per bag" checks.

I would like to recoup some of my money from these checks. Can I sell them? Are they transferable?
