I am so done with Pinpics trading
postal workers are lazy (like mine, he wont TAKE outgoing LBE's can you believe that?!?!?)
This is slightly OT, but useful info just in case this is the reason yours won't take them: my regular postal carrier at my office (who comes round to all the offices) told me that his supervisor said he was not allowed to pick up packages where I printed the postage via Paypal; he was told I either had to schedule a pickup or take it to the post office myself, because they had to have a thing to scan.
BUT! I noticed that in Paypal Multishipping (it doesn't offer this with Paypal Shipnow, so I use the multi-shipping even if it's only one package) it gives you an option called "print a scan sheet". If I print that first, and then print the label, my carrier will pick it up, even though I haven't scheduled a pickup, because now he has a thing to scan. (I have no idea why having a different thing to scan than the barcode on the package itself is necessary, but hey, it means he'll pick it up now, so I'm not arguing.) You still have to hand it to the carrier-- can't just put it in a mailbox-- but it's something.
Anyway, you might see whether your carrier will take it if you do that. It's what I do now on days when I'm not actually going to the post office.
