There are many kinksters who have trouble reading through all these guides and explanations. Most often it's about language barriers. Offer to help and guide through the process, explain it in other words.
Joker created this project because he loves to spread joy... and thus never started to charge fellow kinksters for being integrated into the game (also the printing/ordering of your cards isn’t linked to him in any way… he doesn’t earn any cash with this at all). In fact Joker even spends €50 a month for software and tools, just to handle card creation, your print file downloads, guides and so on.
If you appreciate the time and cash being spent on this and want to help in some easy way… here we go:
Amazon giftcards (amazon.de): https://amzn.eu/d/70zAVcn
Throne: throne.com/joker_jx
Paypal: (only for 50€ or more)
Currently ordering/printing the cards in good quality and same (correct) size with same print-files can be done by only two shops (one for EU countries, one worldwide).
You could help with searching and testing print shops which can print cards of exact same size, with same quality and from same print-files given (and writing the ordering/printing guides)
Contact joker about helping with different things which need time to be spent on (website, insta account, ...)
