Yeah actually in my opinion buying from a store or from Tzadik is better than buying it from us directly, because the more sales these parties see, the more likely it is that we'll get releases/budgets/tour support/etc. in the future.
This is also a good time to mention the filesharing issue - I've heard that a lot of people's justification for not buying the CD is because bands make most of their money off touring and not off actual CD sales. This is pretty much bullshit, mostly because the more albums you sell, the more in favor of your label you are, and the more likely it is for them to release more of your records and give you bigger recording budgets and all that type of thing.
In short, buying from retail stores is good.
