I would buy Asterix Minimates!
So, like BHM and many others, I have been after Minimates since the beginning and I have been most fortunate to have had discussions with many of the "movers and shakers" at DST and Art Asylum before that. I have always felt that Minimates were something DST was behind promotion wise, but once you have a good talk with the folks who produce a toy like Minimates, you learn a lot about business decisions that over power the collector instincts.
We all know shelf space is at a premium and stores want not only what will sell, but will make them money. I was often told that the profit margin on Minimates was small. As collectors, we have high hopes and dreams of licenses and lines that would be amazing, but then Mr. Business would come in and dash our hopes. License holders couldn't justify the margin, stores couldn't justify the margin. Then, lines would not sell through well and get discounted and move to clearance. I really thought box sets would move the line to a better position but then folks scoffed at $30 and $40 price points. I sure did.
I have always felt that Minimates were born for Comics Shops and Specialty Markets. This is part of the reason distribution was often dismal. Promotional Minimates were hard to find beyond the secondary market.
Access via a shop like Luke's really helped with acquisition but I guess the ship was already sinking at that point and I don't think it was because of Minimates. Minimates just went down with the ship.
