OK, here's an idea that I haven't seen mentioned here, and if it was, I skipped over it:
Why can't sites like Melanie's, or even Chronicler's issue their respective products like shareware?
What I mean is, if I wanted to gain access to Melanie's member area, I could PayPal her email addy. She wouldn't have to register as a business, or have an automated shopping cart.
If I wanted a membership, I could simply READ what the membership amount is, and PayPal her that amount. She could then email me an unlock code or password that would gain me **103** to the site.
Similarly, if I wanted a video or whatever else, I could break out the calculator, add it all up, and email Mel what my claculation is for the price for her to confirm, and tell me what the approximate shipping will cost, then PayPal her that money as well.
Granted, it's not as easy and fast to do as just clicking on a bunch of buttons, and tends to rule out the impulse buyers, but I get the feeling that big bust fans tend to be fairly focussed, and will actively seek out a way to get what they want, even it it means that they can't instant gratification...I'll bet that if they really want it, they can wait a day...
For that matter, why can't you use Kagi? Or is it the same deal?
