Heh. I started taking a few screenshots myself, but it wasn't possible to take them on 100% of the actual sites or even their associated forums, and I wasn't about to register all over the place, so I said "fuck it".
I registered for a few but it still didn't help with finding the fees... :/
The biggest pain was Nucleus IIRC which required you to prove ownership of a pgp key before you could log in and I still couldn't even find the fees listed anywhere officially when I got in.
If only there were all as easy as AlphaBay which didn't even require logging in.
