I dont care for the menagerie, and the high prices (i've been guilty of buying from them in the past, but normally stay away.) but he wouldn't be selling, if people weren't still buying.
Why are people still buying from him though? I feel like most of the hardcore collectors that would give in to his prices are people that are probably members here. I've never had to resort to eBay to pay $50 for a $4-$5 figure. Several people on here have helped me out with hard to find stuff and I have in turn done the same thing. I think there's enough nice people to not have to resort to going through this guy.
I purchased a few rarer ones off him before I made my way to this forum, but you're right. People here are so much more helpful than evilbay. I've plugged a few holes here for cheaper than 1 figure from him.
Anyways, as for the clip, I assume inventory on them works like everything else. Buyers buy what buyers buy. They might not want to buy too much and just forget about it, causing surplus stock...
Which menagerie buys.
