tape measure and a scale, pirate ship or another 2nd party shipping company makes it super easy to ship now. literally measure, weigh, plug in the zip and you'll have a quote. you can even have USPS or UPS pick up the packages from you.
PP is already on 1099 that's why everybody wants F&F payment. so either venmo, F&F or USPS money order if you want to Al Capone it.
adios that stuff and treat yourself to a nice steak and the gatitos to some fancy feast!
