I completely missed it so I guess you should do a better job introducing it to your users as a main feature, also create browsers plugins - bookmarklet might work for HN user, but not for 99% others, it also gives you a little more publicity.
Also I did find something interesting from Gadgets section but the width of the "pinterest style" boxes are so narrow, the pictures small and no price tags - it's hard to get my attention at least.
