Good morning, Steve in Alaska;
You are right. The location for the actual information for subscribing is not obvious.
After "clicking" on the "Subscribe/Donate" tab or button on the right end of the row across the top, "click" on the first choice at the top of the screen; the one for "Donations by PayPal." That will open up a new page with rows of choices in various subscription categories. "Click" on the little "down arrow" by each box in the row to peek in and see the dollar amount located in there.
When you have that information, then you can go to the payment method of your choice. Sean even has one for those of us who still use checks and money orders.
It took me a while to find it also, and that was done in part with assistance from Sean.
