Yeah, it surprised me too when I looked at my bitpay account of transactions. The dentist bill on one visit was $440 US dollars which they put on my bitpay. When I got home to look the actual money taken was $411.15 plus a foreign transaction fee of $12.33. So I really saved $16.52 plus saving over 40% on the actual dentist work. I was impressed with their dental equipment, in fact they had some xray instruments I've never even seen here in the U.S. Their dentists are very skilled as well. I met one guy in the waiting room that has been going here for 15 years who also lives in Tucson. Thanks for your reply on my article!
