Okay, that confirms it. You're the one who's not understanding me (perhaps because I'm being unclear, or because I'm using incorrect terminology, I don't know).

I don't want options. I don't want customers to choose anything.

No radio buttons.
No checkboxes
No text fields.
No combo boxes.
No file dialogs.

I just want to have a product that has a one time charge of $15, with a per-product charge on top of that.

Is this possible with a stock installation of Zen Cart? It seems it is not.

I understand that you're trying to help me, and looking through the forums, you've clearly been tireless in your efforts to help all sorts of people. But you're completely misunderstanding what I'm asking here. I understand how to set a one time price with options. I want to do it *without* options.

Nothing to select, just charge the customer a one-time fee, plus a per product fee when they add to cart.

I really am grateful for your help. Your tips to others have helped me more times than I can say.

Thanks again!
