I want to make a simple printable order form for people who want to pay by check. I'd also like it if the form could do the math and then either email them an invoice or enable them to print it already filled in, or both. I'm currently using cart66 and paypal standard for online credit card orders. Can anyone direct me on the best way to do this and/or to an online order form tutorial? I'd also like it if I can simply integrate this mail order option with the rest of the shopping process rather than on a separate page, but it's not critical to do so.
