I haven't had any issues with receiving tickets with each of my purchases.
As for the business model, I know it's not for everyone, but the number of copies of items available for sale isn't fully on LRG, and I've seen a few sales where the game offered was easily still available the next day for anyone interested.
People gripe about Nintendo not publishing enough copies of games. People get annoyed by retailer exclusive variants. Collector's editions are numbered and only available from the publisher. These are all businesses, and they're handling the strategies of selling games differently. Whether it be produce the amount needed for all pre-orders, sell a limited amount due to production costs, or create a false impression of high demand, I think they're usually making these decisions consciously. How many times have I see an expensive collector's item sit on a shelf for months after release, only for it to drop in price to try to get it to move. Product that doesn't move is a loss to the publisher and the retailers. At the end of the day, that means more to them than people saying they'll boycott or complaining. IMO there is no "perfect" business model that can be applied to small and large gaming companies.
I'm always happy to help grab another copy of something for someone if they don't think they'll be able to buy a LRG game the day of. I've done this before for others and am happy to do it again.
