I read a lot where hams complain that the Postal Inspectors won't investigate their complaints of apparent mail fraud. Well, I learned something interesting.
Postal Inspectors are NOT REQUIRED to investigate any allegation of mail fraud involving less than $300.
Yes, you read right -- NOT REQUIRED!!!
That's why professional fraudsters keep their per-hit take under $300 when the U.S. mail is used.
