Parts return allowances

Over the years AC Delco vendors have offered a return allowance on purchases. For instance for every dollar you spend with a particular jobber your parts department can return 5% in obsolete parts. The parts can be anything the manufacturer handles and there are no restrictions on packaging or non-returnable. The obvious reason that these plans are popular is that the parts manager has a place to dump the normal non-returnable parts that are bound to accumulate. I understand that you might prefer a deeper discount instead of the return allowance and that might be a better business decision. My question is how popular do you think these plans are? Do vendors in your area offer them?
