Thought I'd sign up on here to ask a question, but the place looks interesting so I might stick around for more than just the question.
Anyway, my father is having a problem with the calling cards he keeps mailing to his family in Germany. They used to arrive just fine, and his mother and brothers would use them to call him when he (my father) wasn't calling first. Starting a few years ago, but getting more frequent in the last year or so, the calling cards would not show up. It's not hard to imagine someone along the way feeling a card through an envelope and ripping it open with the hope that it's an active credit card or something -- and then deciding to keep the calling card (there have been a couple ones that arrived late in "damaged" envelopes, I guess someone didn't want the calling card).
The only way we've come up with to get around this was to include the card in a package of other stuff. Well, there are only so many times you can send baked goods through the mail before it gets tiring and frustrating. Sending it in a cardboard "priority" envelope is pretty annoying as well. Your thoughts, suggestions, advice? I told my father I'd ask some people in a travel community since they probably do things like this all the time.
