I’ll participate in this. I think it’s a great idea.

I have a couple hundred of these myself due to an order screw up, rather than ship all of them how about if they send you a self addresed stamped envelope and you send them ten orings back in said envelope costs ya two stamps and your done! Use a PM so you dont get more requests than you can fill.
shipping a hundred or more orings will cost way more than one stamp
