I was in my FLGS the week after Wave 7 hit, when I saw the owner talking to a guy by the X-Wing display. I went over, found out he was interested in learning how to play so I set up a game and gave him an introduction.
A while later, the owner's husband came over with a puzzled look, holding a K-Wing and a TIE Punisher. He asked me which one was better. I told him it depended on what you wanted to do. He asked which one I would get next, and I told him probably the K-Wing. He handed it to me and said "Here. That guy you showed how to play bought $200 worth of X-Wing stuff, and made a point of saying what a good salesman you were."
Does that make me evil as well, or just an enabler?
Neither, just a good salesman.
While the margin-hoarder in me cringes at giving away $20 after just a $200 sale I do find myself impressed with the shop. Hopefully they ask Gullwind to organize X-Wing demo days or regular play nights in exchange for a permanent 10% discount.
