The FLGS when I was in high school once told me that to replace the Hive Tyrant I was buying, he'd have to buy $250 worth of random GW shit, because GW wouldn't just send him a Hive Tyrant. And that was decades ago, $250 wasn't a small order.
The FLGS I go to now has an ungodly small amount of space -- maybe 200 square feet for the entire store. And an entire wall is dedicated to GW products because GW forces him to do that if he wants a partner account with them. This includes a 6 foot tall wireframe display rack of Citadel paint, many of the pots of which are ruined because it's hard to shift some of the paint.
Every army of the week he has to fully stock, even if it never shifts, for example. And don't get him started on Codexes, they're completely useless after a certain point and he can't get a refund or anything, but has to carry all of them.
GW's business practices are downright toxic.
