On the other hand...
I was in my FLGS today and bought two books ("Hunter: the Vigil" and "Star Wars: The Clone Wars Campaign Guide"), setting me back almost £50.
Now, it's obviously true that I could have picked them up for less from Amazon or the like. (Actually, a lot less - the Amazon discount is about a third.) I shop at my FLGS as a matter of principle, and that does mean paying a premium.
Still, it's a lot of money for not many books.
The thing is, if I run a campaign of Hunter, then it will absolutely be worth it. But, despite a couple of very solid recommendations, there's no guarantee that I will - I may not be able to get a group together, we may not be able to sustain a campaign, or we may decide we'd rather play D&D instead.
And while I'm very confident that I will run a Star Wars campaign, or more likely several, in the future, I am by no means convinced that supplements actually help that game - in fact, I often feel games run better without them.
I find myself somewhat uneasy about this. I now have enough gaming material on hand that I will have to live to be about 300 to use it all. And the books are now edging towards a price point where I have to be more selective in my purchases - I won't be buying many books unless I
know I'm going to use them heavily. (Indeed, a major factor in me not trying WFRP 3e is the cost - my impression of the previews is that I probably wouldn't like it, and at £80 RRP, it's too expensive for me to give it the benefit of the doubt.)
I don't envy RPG publishers their position. I'm not really interested in learning Yet Another Game System, which limits their ability to sell me core rulebooks (and besides, I doubt they can live on core rulebooks alone). And yet, the return on supplements isn't terribly good, and diminishes with time. So I don't know what they can really do.
(Perhaps the wisest thing would simply be to write me off as a customer.
