On one of my websites i want to add the option for someone to buy a item and once they buy it, a email will be sent to there email adress with a attached zip file i see many sites and ebook sites use this. I am hoping someone here knows a script that will allow me to do this that works with paypal. I seen some around on websites for around $20+ but im not sure which one is most reliable. Thanks cant wait to hear what you guys think.
