Welp, there ya go! ;B
So this campaign is going to be per-page + free goodies for patrons. So the thing that everybody gets no matter what is one page bimonthly (unless people tell me they want pages more often, which I wouldn’t blame them, this is gonna be 26 pages), so you’ll get charged your pledge amount no more than twice a month. (I have not decided what days those’ll be specifically, but seeing as how I did the first one on friday, it might be like 2nd and last fridays).
You will ALSO get other stuff without being charged: smutty doodles, full-on illustrations and the like, and you’ll get them higher-res than I post to my site. Those things aren’t guaranteed on any sort of schedule, they’re just freebies I’ll throw in as the inspirations strikes.
If you pledge more than $5 per paid post, you’ll get entered into a pool to win free art every month – and if you’re the only person in that pool, then holy shit, you get guaranteed art every month.
When I hit $60 in total pledges per paid post, I will start putting up WIPs for all the stuff I post as a sort of “thank you” to everybody helping me put food on the table haha.
I hope that answers your question!
PS – you can set a monthly charge limit too, IIRC. Not sure how it works, I haven’t done it myself, but you can tell Patreon that you only want to spend, say $15/mo, and I think that applies to ALL your subscriptions. Not sure, you should look into it if you want to be careful about getting charged an amount you weren’t expecting.
