Hey Marcel!
Lots of people use the forum. I suspect there are two reasons you aren't seeing a lot of replies.
1 - We don't allow buying / selling / advertising in the forums. I suspect most people just aren't wanting to jump in on a thread they expect will get closed.
2 - The Jason England Gimmick Dice were a VERY limited edition product from years ago (2012 I believe). We sold a VERY small number of sets from Jason's private collection, and they have not been made available again since. 9 years later, it is going to be extremely hard to find one of those people who purchased these sets, and even harder to find someone willing to part with a set. The majority of forum members here won't have been around that long, and have probably never seen these advertised.
Sorry I can't point you in a better direction. Good luck on your hunt! I'm sure there is someone out there who would be willing to make a deal, it just might be a challenge to find them.
