Another question about the e-junkie notifications.... I just started taking PayPal in addition to Google and I notice that the info I get back from a PayPal payment is not the same as Google.
The one thing I'm missing from PayPal is the mailing list status. I don't know exactly what a buyer sees when they checkout (idea: have some screen shots on your site for merchants to see what it looks like?).
When they pay with Google, I get a flag called mailing_list_status true or false. I use that to add folks to my mailing list. Would love to have that flag with PayPal payments as well. Is that possible?
