Many buyers think they are doing the seller a favor by sending payment as Friends and family. For the pmost part is is a pain for the seller
When that it done:
1. Your physical address is removed.
2. Direct printing of postage is more difficult.
3. It does not show as "Print shipping label" to the seller which helps them keep track of what needs to ship.
4. Print postage from USPS.com does not have the 1st class mail option.
5. It removes the shipping discount offered by Paypal.
My smart daughter showed me a work around.
https://www.paypal.com/shiplabel/create/
Using that link you can still print postage through Paypal with the discount.
Tracking is a little obscure as you need to got to "payments sent" to find the tracking info.
You can use that link directly or if you have printed postage from another transaction remove the last section of the URL to get there.
You do need to manually cut and past all of the address info and email to give the seller notification.
Hope this helps other sellers.
