Yes the $3.00 is the price for the BASE game which, but you can go straight to the $10.79 one, no need to get the $3.00 first, then PLUS.
And again, yes, once you buy it you'll have all the future updates, I do NOT make you buy it again once it gets updated.
I have no idea exactly, I guess PayPal and straight up cards like Visa/Mastercard?

Thank you for getting back to me (us) about my (our) questions. I added the (expands) since I am sure with some comments from other postings seem to indicate they have questions but not sure how to ask them. Now I have information I can work with and so do those out there that had the same question(s).
Stay strong and stay fresh! And I am still hoping for more soon on your other games once you catch up enough to start the mind's eye and inspirations toward those story lines.
