These were larger amounts of cards, and many were not easily replacable. Photo mailers were not going to happen (not on my watch, anyway).
Got the 2 packages sent (for much better prices than sending from the US, and no customs forms - written or online) on Friday, after round #3 of golf. :) Got to spend some quality time with my wife's side of the family (the better side, frankly), and had a very enjoyable time. Only drawback was the fact that we arrived there around midnight Tuesday night and had to leave around mid-day on Sunday - only about 4 days there this time (previously, we've been there for more than a week) and had no time to plan to try any meet ups.
Thanks again for all the advice and links. I am pleased with the outcome (provided they arrive safely at their destinations).
