There are at least two additional price problems that I've seen:

LeaAnn V4 is listed at $6.60 but the link http://www.renderosity.com/mod/bcs/index.php?ViewProduct=53567

is priced at $8.80 [20% off rather than 40%]

also

Mountain Passes is listed at $5.97 but http://www.renderosity.com/mod/bcs/index.php?ViewProduct=39704

shows it at full price of $9.95
