You're right JustaPlayer, since they often got the wrong author(s) and no cover image, which tend to corroborate your guess. When it happens, it's a good idea to preorder with Amazon. I just received the B5 Mimbari Sourcebook for the ridiculous price of 23$ (CAN) ! They have since corrected it but it's still pretty affordable with 30% off :
US List Price: USD $34.95
CDN Equivalent: CDN$ 46.01
Amazon.ca Price: CDN$ 32.21
You Save: CDN$ 13.80 (30%)
As much as I like to support my local gaming store (LGS), I would have paid double for the same book. So instead, I bought the Book of Dragons
I get Hardcovers sourcebooks for the price of Softcovers, sort of. I still buy about 60% of my RPG stuff at my LGS, though.
