OK I have an existing OS commerce that is fuly installed and functioning at this point. Everything is tested and working.
Now people can buy stuff on my site that I can once they are paid the product I can ship by mail. Now what I need to do now is to sell videos, and those are downloadable videos. So same process, someone buys my video, he pays for it, then gets an invoice by email like OS commerce always do, but where your work starts is there, on that email I need a link to be sent, that link wil ppint to the ziped file in a folder on the same server that will contain the videos the clients purchased. then he can download it and its all done. What I need is this link to die after 3 days then its no longer working.
So I do not need this whole thing to work via the admin, because the files are large so they can somehow be uploaded by me via FTP then entered as a product for sale on my OS commerce. Unless you have a better idea please let me know but I need this to be kept simple but efficient.
