In other words, your email address for permies.com can be different from your email address for PayPal. Everything will work fine.
Subject: Pies purchase - email address question
My email address for PayPal is different than the one for this site. When buying pies by PayPal it might be an issue - can I enter another email address (good for permies.com) in the "Information for the seller" field, would that be enough?
