International Price Calculator
See bottom detals and price under "First-Class Mail® International Large Envelope"
If you dig a little deeper into this, it says that the envelope "must be flexible" - here's the link:
240 First-Class Mail International
That could mean the buyer gets a creased card. The choices aren't good - you can either risk having the card get damaged in transit (which can happen even with a bubble mailer if they try the "flex test" shown in the picture) or you charge $7.50 in shipping and no one buys your card. Which way you go depends on the value of the card and how much of a stomach you have for risk.
