Wow, thank you both for the great info!!
Bellini, I'll try that in about an hour and let you know how it goes.
The reason I wanted to get this info in there in the first place was because Paypal makes it easy to print a label using that customer address info. However, it just dawned on me today that the customer's paypal address might be outdated (as opposed to what they listed for shipping in the store), in which case the package would be sent to the wrong address anyway. Hm.
Ok let me try this code change to see if it brings in the name and email to Paypal at least. Slightly off topic: If you don't use Paypal for shipping the orders, what do you use for printing packing slips and generating labels?
Thank you so much to both, I really appreciate it. I'll post again with the results of the code change soon.
Cheers!
