Does a Postal Money order need to "clear"?


I sent a Money order to my seller and he says he will ship when it clears. Is this necessary?

Postal should not. You probably paid for it with cash. A money order from a bank does have to clear.
When it is deposited, it could be returned. UsPS does maintain a 'stolen' do not pay list, which is sometimes checked. It does not hurt the seller to wait 10 busines days to be sure.
You can take a postal money order to any post office and get cash immediately, assuming they have enough money to cover it.
They are counterfeited so I can see a seller might want to wait. They can go to their local post office and verify that it is genuine and not stolen.
I can see the seller wanting to wait if he deposited the M.O. directly into his account instead of going to the post office to cash it.
