I asked Koby at EveryPlugin for Stereoplacer with the voucher and he wrote:
”Sure. Stereoplacer would be $15.96 keeping the same discount ratio we offer for all Nugen products.
It may take longer to deliver because we need to ask for their approval per each transaction, so it'll end up mid next week.”
Koby rocks!
I'm still wondering. Part of me thinks all of these will turn up in the next Reason Suite. Another part thinks they maybe had a time limited deal with UJAM to port and sell these, although that seems a bit weird.
