There is a saying. I hear it mostly in mechanical engineering but I have heard it elsewhere:
If something is fast and good it isn't cheap.
If something is cheap and good it isn't fast.
If something is fast and cheap it isn't good.
For example, I ordered the new
DA codex from Discount Games Store for almost 50% less than I would pay for it here in Canada (the US cover price is $10 less than the Canadian Price even though the Canadian dollar is between 1 and 2 cents STRONGER than the American dollar, plus no Canadian sales taxes (about 13% in Ontario), plus their discount takes a total of about $30 bucks off the total price). I'm still waiting for it to arrive, but it will be just as good as if I ordered from
GW but cost much less.
Ordering direct from
GW is probably the fastest and most reliable way to get your stuff. However, you have to pay their MSRP, which can be insanely high in some cases.
Going the ebay route can yield fast and cheap product, but also unfortunately can result in a lower quality due to poor shipping.
If you don't mind waiting a while, try
