Amazon is pretty awesome. I know they aren't a "hobby" vendor but I ordered a non-hobby item from them and received the wrong item. I made the claim online and they shipped the correct item immediately before I even shipped back the item I received. The next morning UPS picked up the incorrect item from my doorstep. It doesn't get easier than that. I never even talked to anyone. I just signed into my Amazon account and went to the order and selected "Return" and chose a reason why. They redirected me to a packing slip and shipping label. Took all of ninety seconds.
