Ive lived through numerous price hikes and I still continue to buy from GW. The interesting change in my buying habits, though, is that I now buy large, expensive kits from online retailers at significant discount. Saving a few bucks here and there doesnt mean much to me on smaller kits, so I support my local hobby shop with my business (seeing as I play there). But I would be a very silly consumer if I didnt see the value in saving nearly $20 on a Soul Grinder.
The interesting thing we will have to wait for is if GW will over extend the value proposition with its products in the near future. Basically- will GW finally hit the price range that the majority of their customers will not pay their prices and shop elsewhere. I have thought about starting other games (not stopping 40k mind you) but I am limited by hobby shops and hobbyists in my area that play different games in any significant number.
