If you “didn’t know what they were” how did you come up with a price? I would assume you would glance at a scope to come up with a value for your buddy’s stuff and not give his stuff away on them. And then you traded for other stuff for them, I’m sure they gave you stuff to put out cause they wanted/needed money not to get more primers and reloading bullets. Almost sounds as if you were trying to take advantage of the giver and the receiver which you were successful at which is why your getting flamed.
