I think like one UPS store in Vancouver sells U.S. stamps, I don't know how it is where you are; just phone around. To add something to my above post: Paying about 20 bucks for the universal stamps, bubble envelopes, and postage to mail it in the 1st place may not be neccesary, but was the best option available to me. You could just send the S.A.S.E. with American postage on it for a lot less, but the risk is up to you. Customs doesn't open EVERY package they see, but if yours falls victim to a random check you could lose your crafting mats. Honestly, the best way to get crafted cards right now is to get them off people in the trade forums. Naecabon has lots, you'll get them just as fast or faster (unless you're on new-trader-sends-first status), postage will cost like 1 stamp, and there's no risk.
