[Elecraft] IRCs

[Dauer, Edward]

Arguably a bit OT, but I suspect the collective wisdom on this reflector can help with this question -

IRCs (International Reply Coupons) are no longer sold by the U.S.P.S.  - a major loss to QSLing with stations not part of LOTW.  My experience sending green $tamps has not been nearly as good as it was with IRCs.

IRCs are, however, available for purchase in other countries, including (so says the Internet) Australia and Canada.  What I have not been able to find out is whether an IRC purchased in country A (e.g. Canada) and sent to country B (e.g. some DX entity that's part of the international postal union)  can be used in country B to pay for return QSL postage from B to country C (the USA) - that is, a country other than the one where the IRC was purchased.  The idea of international reciprocity would seem to require that among member countries, but I haven't been able to find anything reliable (or otherwise) that clearly addresses the question.  Does anyone know?
