Well, just to update again, (if anyone cares) the transaction posted to my account with what I see as a pretty good exchange rate. They gave me a rate of 7.708. The day I made the purchase I checked the forex rate on xe.com and it showed as 7.74. So, while the rate is a little lower it is better than anything I can get from the atm using a master/visa debit card, as most take off 1% minimum, giving a rate of 7.66. Or using master/visa for purchases also carries a minimum 1% fee, usually 3%. When you add to it that UnionPay is the most widely accepted network in China I think this is a good deal. I plan to use it is much as I can for my expenses here.
