To my pleasant surprise he instantly messaged back to let me know there is a summer sale discount of 50% if you use the code "summersale"

I highly suggest you check out his refills! Some of them have very intriguing audio demos and the sound sources are pretty unique and fun.
There is an All Refills bundle which I got for 50€ with the summer sale discount
