Instabill.com has changed and does not let me sell my php scripts any more. What is another place that I could use that is like instabill.com and will let me sell my scripts.?

Try www.revecom.com i think they allow it. But you're better to ask them before.

try digibuy

http://www.ccnow.com is another one. You might also consider PayPal (although I don't think you could automate script delivery with them).

Personally I reccomend Revecom.

http://www.revecom.com

I think CCNow won't allow intangible products such as hosting or your Php scripts, you can refer to this page http://www.ccnow.com/details.html#products
