It’s pretty easy for me to bring the old part back in and get my deposit back, but there are also other ways to promote recycling. Parts stores could offer a small financial incentive for bringing in your old part. If they want to profit off of your old part, they could at least give you $10 for it, or some type of coupon. Whoever is profiting off of the old part is still winning, just not as much. It also creates a better atmosphere in the store. Not everyone gets mad about seeing a core charge added on the total, but there’s no way it makes anybody happy. Some kind of incentive for an old part would make anyone feel good. Getting your deposit back doesn’t promote the same kind of good vibes. Are there any online stores that don’t have core charges?
