Re the scenario in the first post, most non-dealer members don't take credit cards. From the seller's viewpoint, I wouldn't want to get in the middle of something like that anyway. (A few folks in blue/silver do; why are they not required to be in the dealer halls?)
I've picked up new items for friends that I trust. Doubt that I'd do it for a used item, as condition is highly subjective, and I wouldn't want to be blamed for not noticing a defect on something.
