Has anyone managed to get postage and customs forms done online for USPS First Class Mail International? Last time I shipped a classic bicycle part overseas I was in line at the Post Office for too long. It seems odd that the Postal Service would insist on a face-to-face transaction for mere First Class mail. It's like selling jewelry and watches as self-serve items, but bags of peanuts exclusively from behind the counter. Neither eBay nor PayPal nor USPS Click-n-Ship offer this option, but I saw somewhere that certain authorized postage providers can do it. Who might these providers be?
