i think i got a patron acount but but for another game i did like the 5$ thing
In that case one option would be to make a subsciption (and cancel it immediately since you don't want an on-going payment) to get the reward of seeing patron-only posts for that month. Just keep in mind that it's set to charge immediately, so if you pledge in the middle of the month it's only valid for the remaining time until the next month starts.
(The same reward tier also includes full size CG previews and all old previews.)
