Inprint (Patreon)

Hello, 

I checked the promotion code for my Inprint shop and it appears I could make one easily!
The only thing is: I have to give a limited date! Would you be interested to have prints? For how long should I  let this discount?  
I was also thinking about letting this discount for my twitter followers but I'd prefer my patrons to have an advantages. So let me know what you prefer :)
