Raffle calendars (Patreon)

Approaching 2020, therefore, need a fresh wall calendar.
As you know, I have two calendars for 2020: 16+ and 18+. I decided raffle calendars among their patrons (subscribers) tiers for 25$ and higher. Exactly one week later, on November 29, 2019, two winners will be selected by random. One will get an 18+ calendar, the other will get a 16+. And there will be a consolation prize for third place ;-)
Sending for my expense (and the some very strongly worry about this about) ;-)
