Show HN: Send your photos as real postcards to anywhere in the world for $1

Title send postcards 'to anywhere in the world' is misleading!

From FAQ:

Can I send postcards outside India?

Not at the moment. We’re working on it.

Sorry, the FAQs are not updated at the moment, we do ship internationally!

Lost me at "To continue, login using your Facebook account."

Noted about this, we are making a login with email, this was just easy to get started.

How do you differentiate from all the other companies that offer this service?

postable.com is an option that works in the US and internationally.

how do you monetize on this? I tried doing some basic research few years ago and found that monetization was impossible.
