This Christmas, I shipped gifts (pastries, mostly) from a French pastry company (Pierre Hermé) to eight French friends and one Italian friend. The Italian one was extremely expensive; I didn't notice at the time, and when I did, it was too late to cancel. (I have a hunch it had something to do with crossing the border; if I ship something to Canada, the price goes way up, too.) The French ones cost about 32 Euros each. I was tickled by the idea -- look how cosmopolitan I am, with all these French friends -- and didn't do the math. One shipment was about $35. Eight shipments was....hum.
So I thought well, hell, I like to bake, home made is best (maybe....), why not bake stuff and mail it? Cut the shipment costs way down. So I spent a little time looking at the Fed Ex, UPS, and USPS sites.
As a general statement, it appears that the minimum cost to ship a one pound box to France is about $6.00.... but thats just a guess. The Post Office makes it hard to ask the question; their web site talks a lot about rules, guidelines, standards, and so forth; very little about what will one pound from here to there, cheapest rate, cost me? The Fed Ex and UPS guys are clearer.... and cost about $40 a box.
Maybe next year I will just send a card...
