I do a lot of BnPs and I have a question about the best way to do a BnP that's outside the country. Usually, I tell people to send a sase, but, I cant mail a package from the US with (for instance) Austrailian stamps. The last person to request a BnP from me suggested sending a couple of extra blanks to cover postage, which is fine with me. I don't want cash involved, but I'm not sure if this violates the "2 for 1" restriction, plus I don't really think that the blanks cover the cost either, since postage will probably be $3 or $4. U2Lynne suggested using international postage vouchers. I did this once, but because I live way out in the country, my local post office had no idea what it was. I ended up driving to the city to use it (which cost more in gas than it was worth) Any ideas on the best way to handle this?
Thanks
