Just a suggestion, don't ever mail in a plain envelope! I have had a few items sent to me that way and when/if they arrived they were either severely damaged or missing from the envelope. The sorting machines rip them open as they are set to only sort items which are flat.Then you lose your ring and credits. I was told they clean the machines with a shop vac so, they are lost for ever. Just a suggestion.
S2033 is right, someone sent me a mp3 player I won on here in a envelope, All I got was the stuffing and then ripped up envelope, I had filed a lost report incase it ever got found, well it never did of course.
