Why don't more eBay sellers use YouTube in their listings?

I've often wondered why more eBay sellers don't include YouTube videos modeling their items.  I recently came across this seller featuring Tom Ford over-the-knee boots, very nicely modeled in a YouTube video.  Although I would have preferred a little more walking, I suspect the seller didn't want to put too much wear on these brand new boots, which by the way, were listed for $3,200!

Blue Biondini Boots and a sexy video

These vintage 1980s Biondini blue leather boots with snakeskin detail and sexy spiked heels sold for their opening bid of $49.99. I think there would have been more interest in these if they had been larger than a size 7.

I especially enjoyed the way the seller was able to provide some very sexy modeling with the YouTube video, although I was intrigued by the black animal (panther?!) which walks across the path halfway through the video.
