Hi Joe
I think it would be like a craftsman tool item, they don't care they will replace it if it's do to bad mfg. or a error making the bit.
But I think you would need to get them for 2.oo a bit in order to resell them but on the 2nd item he has listed it would be about 5.oo dollars a bit.
But like you I don't think they will sell but you never know about items on ebay, I see items go for list and over list on eBay,, is a funny place..
