Not important: So some years ago when I wasn't artist and I wanted to be artist, I downloaded a pirated version of Photoshop to try and doodle on it, I still use it, but honestly I don't like having pirated software, mostly if I'm going to profit from it, the thing is that I can't afford $600+ for Photoshop, otherwise I would already bought it..
So I was looking and testing different art softwares for days, and I found this one called IllustStudio, it's almost powerful as Photoshop, I've been drawing and testing it, and I'm loving it.. the only bad thing is that it's only in Japanese language, still there are some non-official english patches for it that I'm using.

I want to buy IllustStudio, but I don't know how, I've been searching on CLIP store, I've found some IllustStudio related stuff, but I think some of them are tutorials, and some kind of monthly payment version of it... How / where do I buy the full digital version of it? if that's even possible..
