The Cost of a Postcard

I'm really interested in learning about life in other countries and I just thought up this swap idea today. You'll send a postcard to your partners and on the back of the postcard write how much it costs to send a postcard internationally and what else you can buy in your country for that amount.

Here's an example: In the US it's $1.15 USD to mail a postcard internationally. With $1.15 you could buy a candy bar or a bottle of soda. Aside from that you can include other details about postage too. Is it expensive to you, or cheap? How much does it cost to send a card to someone in your county? Has the price increased lately? How much did it cost when you started swapping? Etc.

The postcard itself is sender's choice. No handmade unless your partner has it on their profile. The card should be sent naked and written on.

Newbies allowed with filled out profiles. I'll be double checking just to make sure there's no one with excessive low ratings.

Let's have fun :)
