Thanks! Do I need to deal with customs or anything like that? And does the USPS flat rate give proof of delivery?
Lastly is there any way for me to capitalize on this guy, to add a handling fee so to speak? I already chose calculated shipping.
You don't have to deal with customs.
Just fill out the customs form when you ship it (declaring the contents and value)
USPS Flat Rate if printed the label online will have tracking information that will be suffice for delivery.
Make sure you insure the package.
You could add a handling charge, but very few people charge that.
