Oh man, I so wish I was home right now to take some pictures! Alas, I am away to school.
I work at my local bookstore haha (best job ever, btw) and I focus most of my attention on the young adult and graphic novels section. I have to say, we didn't have many copies of the series in our store at all (it's just a Borders express, very small and without as wide a selection unfortunately) but when I read the Alchemyst I ordered some more copies in, and was pushing the series a lot with customers. Of course, since I'm not there to continue doing that they've probably been returned or sold out without being restocked >>;.
When I left, though, The Alchemyst was part of a buy 2 get the 3rd free sale so it was in a display on the front wall, and there were a few copies of The Magician and The Sorceress in the regular young adult section. No face outs because there weren't enough copies :[.
