Historically, next year's passes have always been the cheapest the first month or so they go on sale. I have not seen Cedar Fair do a Black Friday sale. From here on out, the passes will continue to raise in price. If you look at the first post of this thread- I used to track price changes a few years ago. Take a look at that for comparison.
Also, they do let you buy your pass outright without signing up for the payment plan. It's just not default option at checkout. At the page where it gives you the payment schedule, there will be an option to pay in full.
