Taking a slightly different tack, the 11-spoke alloys being sold by the guy on eBay were undoubtedly at a bargain price. I bought a set, unsure whether I'd fit them or not, and then later sold them on via LOC at the same price I'd paid for them.
I would have felt uncomfortable personally snapping up more than one set on eBay to make a profit on, because I (again, personally) would have felt I was potentially depriving other LOC members of a bargain.
Not trying to dictate what everyone should or shouldn't do, but profitting on items which have been pointed out to LOC members doesn't feel in the spirit of the club to me. Others may of course disagree.
Just my own thoughts.
