A friend of mine had been collecting bills and currencies from all over the world as souvenir from each country. When she learned, though late, that the Philippines now have a new set of bills, she asked me if I can send her some for her collection.

Apparently, I do not know how to do so without ever being flagged. I mean, the post office as well as all other couriers are strict with money inside packages and all. So I told her that I will save her some stash and when she comes home, she will have them through our usual exchange, she agreed.
