IF YOU DON'T HAVE DELIVERY CONFIRMATION NUMBERS FOR PAYPAL IT'S NO USE FIGHTING AS I ALSO LOST A CLAIM, THIS IS ALSO GOOD FOR OUT OF THE USA, AS THERE IS NO INSURANCE ON FLAT RATE PRIORITY ENVELOPES, ALWAYS ASK YOUR BUYERS TO SEND YOU AN EMAIL STATING THEY WONT HOLD YOU RESPONSIBLE IF THE ITEM IS LOST WITH THE FLAT RATE ENVELOPE SHIPPMENT, NOT SURE IT WILL HELP BUT IT CANT HURT EITHER OR JUST DONT SHIP OUT OF THE USA. CUSTOMERS DONT ALWAYS HAVE TO INSURE THE ITEM BUT YOU DO HAVE TO SHOW PROOF OF DELIVERY CONFIRMATION NUMBERS. PAYPAL IS SUPPOSE TO BE FOR EVERYONE BUT DONT LET THEM KID YOU, THERE NOT!!!!!
