I am looking to create a payment form where I can collect additional info from the user, like their e-mail, their preferences, etc... I know there are third party websites like Wufoo that can handle this for you, but is there a way for me to do this without having pay for a form builder? I'm just looking to collect some info before they hit my paypal buy now button. I thought of creating a redirect after the purchase to a form to fill out, but I;m not sure how I would keep track of which form is for which order. Any input is highly appreciated. Thanks.
