"they"
I kinda recall Miha is a one horse shop. Maybe he's busy? He has a FB page and has posted an alternate email address when people have complained about not getting a response.

Been my experience that Miha has historically been pretty poor at responding to emails or keeping his web site up to date. Makes a great mold but I've not found him easy to get hold of via email.
but he raised the prices 12% before he posted the 25% off. The Christmas 25% 4 cavity was $93 now that same mold is $105.87 So you are paying the same price he had them at before the sale. Still not bad but I hate sales tricks
