Hi Pat,
Yes I lost a RR before. Actually it wasn't even mine. 20 LE chips. I sent it on to the next person and it never arrived. Sent priortity insured. Luckily the Post Office had to pay and that helped the RR's owner. Package never did show up as far as I know and was never returned to me as the sender. Some postal worker is now a chip collector.... ahhh a new way to recruit members<G>.

Hopefully your last sender did insure the package and it can be traced.
