how do i make a downloads store
how do i allow people to pay to download things off my website?
are there any ready made scripts available for this?
There are no free scripts that authenticates the user to download stuff once they make payment. If there are I haven't seen any as of yet and I had like know if some finds it. What you need is a store front, basically a shopping cart with your products, then you can allow the user to download after they have made payments via CC.
Are you programmer? Then you should be able to do it, if you are a Business Developer/Mgr/Assoc. and are interested, let me know, I can do it for you.
