Nice sleuthing.
I usually scrub my addresses of extraneous tracks (hey, how else am I going to take credit for someone else's work), but unlike You-Tube, where it's easy, it didn't work here, and I couldn't find the link straight through Amazon without more work than I thought it was worth.
I don't know for sure if that linkage means a purchase at that site pays money to the linking site (it's often true at Ain't It Cool News), so if you don't want your cash going to the lizards, I'd go to the extra work of trying to fish up a clean address on Amazon.
