I came across in one of the other threads how someone found the Star Wars Visual Dictionary (Darth Vader on the cover) at a local Barnes & Noble for $5.98, and it was also on the B&N website for both that price AND $15.98. Well, I got around to ordering one for myself (at the lower price, of course), and to my pleasant surprise, also found the Star Wars Episode I Visual Dictionary (Amidala on the cover) and the Star Wars Episode II Incredible Cross-Sections, all available at $5.98 (or $15.98, if you're a masochist).

So get them while they're in stock, and before B&N catches their mistake.
