I just bought new IRCs at post office. Its been 10 yrs since I bought any, but I thought they had to be stamped in the left hand corner when purchased. They did not do this, and said they have never heard of it. Has something changed over the years. It has printed US 2.10 in the block, but no stamp. Maybe someone can help W3BJ John ____________________________________________________________ Weight Loss Program Best Weight Loss Program - Click Here! http://thirdpartyoffers.juno.com/TGL2131/c?cp=JKMxkhMvqbzOoFEbv7BGPgAAJz2j3Y52xjY0eyXi3p7XDsnkAAYAAAAAAAAAAAAAAAAAAADNAAAAAAAAAAAAAAAAAAAEUgAAAAA=
