I have a question I'm doing some promotional flyer's for my CD project and i would like to put a discount code on the flyer for people to receive $2 off my $8 CD thus making it $6 for the people who get the code from the flyer and use paypal...

Is there a way of doing that (USING A PAYPAL BUTTON) so as they fill out the form it gives them and options to put in my specified code and get the $2 off and them continue on using paypal???

I tried the calculation script thing it would have been great but I could not get it to work when I edited it down to just one item...

Thank you in advance,
