Question

How do people i the post office know in which letter there is money?

Answer 1

THey handle mail all day.  So it doesn't take long for them to spot a letter that feels really light but doens't have a big piece of paper in it, ie it's a check!  Pretty much anything that looks like a standard birthday card could be suspect too.

THe best bet is to not send cash through the mail.  You are risking losing it and whatever it as in too!

Answer 2

They also look for the welfare check people get (SSI) at the beginning of the month, Birthday cards, it's easy to see through a envelope all they have to do is hold it to the light.

Best advise NO CASH money orders (filled in) or western union
