Uhmm, BTW Ryan, is there a way to know how many units of every product have been sold? That's the sense of having a "Best sellers" block and by now my code just displays the most expensive ones since I haven't found where are the number of units sold for every product (well, or catalog unit, considering classes and atributes). I had a look at the excellent uc_reports.module but couldn't find an easy way to select those "best sellers". Any suggestion?
