The second Franc Franc transaction posted without DCC, as expected. I'm still waiting for the Courtyard transaction to post. I didn't keep exact tabs, but I pieced together about $200 - and this is a conservative estimate - of money saved by opting out of DCC.

Furthermore, this only includes the known DCC transactions. There were about $2000 in charges in Taiwan where my wife proactively requested NTD. Many of these stores wouldn't get any foreign cards, so it's unlikely they'd have DCC. I'm giving them the benefit of the doubt, but it's really difficult to tell how prevalent DCC is in Taiwan outside of department stores and hotels.

In total I also probably saved close to $250 by using a 0% FTF card versus one with a 3% FTF. So without too much work and using the right credit card I was able to save at least $450 on expenses. Don't allow yourself to think that it's only a few dollars for DCC. In aggregate these charges do add up.

During future trips overseas I will meticulously track the pending/posted amounts and DCC offers. We should add a running total to the wiki about how much we've saved by just saying no to DCC.
