Did you guys considering selling it on other platforms besides eBay? (I don't know of any; I'm asking out of curiosity of whether there's any competitors for hosting an auction like this)
P.S. I looked at your site -- I took 252r this semester and loved it, though the topic was different this year.
I don't think so. Back in 2009 I was responsible for adding another carousel monstrosity to the world and that was just before smartphones exploded. Certainly not what I had in mind.
The screenshots near the top definitely look like part of the web page -- I tried clicking them at first. A border of some sort might help distinguish it (I didn't see the three dots at the bottom at first, and most laptop screens probably won't be able to see it either).
