We sell folded charts at cost (read: 40% off), and they usually take 3-7 days to get to you -- this is at wactac.com. We just started doing it, and we're not perfect at it yet, but of 200 orders, I think we've goofed up on 3 of them and made it right either by refunding the order, offering free charts, or just uprating the shipping options on-the-house.
For book products (AFD/TPPs), they're so heavy that they cannot be economically shipped, even via media mail, unless you're buying a lot of them. The local FBO is the way to go if you need them "now", and the NACO subscription service is pretty good for recurring subs, based on the free shipping.
Personally, I am in favor of supporting the local FBO, but NACO is making that increasingly difficult (which is why we started selling them at cost to begin with -- so the FBO could still keep stock and not be penalized the full 40% by switching providers) -- so your options are getting more and more limited for this stuff.
