Looks like it only works on full price items. I tried it on a Surly Pacer frame and it worked fine, but it wouldn't work on the Fuji Tahoe 29er they have on their homepage that is seriously discounted. It also worked on a Surly front rack that their price was slightly below MSRP on. Looks like it is just a try and see thing.
