FFG marks their OP, game night, and promo kits, tourneys, and promotional items as “not for resale” and they end up on eBay all the time, completely intact. They’re either being resold by store employees or given out as swag to customers who flip them. It’s just not worth the effort for FFG to prevent this stuff from being scalped. People got bent out of shape about the X-Wing limited Naboo ship, and that was done as a raffle, direct to customers... it doesn’t get more fair than that for something limited.
Honestly the only thing that makes sense to do is accept that limited edition stuff is going to come out as raffles, preorder promos, convention swag, etc., and just live with it if you don’t get it. Honestly, going to conventions or tournaments can be really expensive if they’re not near your home; I can’t bring myself to get mad at someone who offsets the cost of the trip by flipping something for more than they paid for it.
