I don't know about Snap on. But my brother in laws neighbor works at a county land fill that service's several retailers. He is always bringing home tools that someone has returned. Most just need some minor work to fix.
He has giving him several cordless dewalt tools, small trailer (not a lawn mower trailer either) chain saws (clogged carbs), socks etc. that just had the package opened and couldn't be sold at wally world, all kind of stuff like that.
He kept a cement mixer for himself just needed a switch to work.
The store just tosses them in the trash. Go around back and you will find a locked dumpster for returned merchidice that can't be resold but they don't want someone digging in and trying to return them again. A friend that works a Home Depot told me about this. They toss returned tools including sockets sets with missing items in the trash. They say it cost more to sort, repair and send items back then to just trash it.
I road with Cornwall tool dealer one time and he said some airtools are repaired and returned at the request of the dealer.
