These are the valid stamps to be able to send something from BRC to a non-US destination.
You might not be able to grab these at the Reno airport/shopping, if you don't plan ahead (post-offices are mostly open 9-5 Mon-Fri) as most retail outlets only stock domestic stamps. If you can avoid buying in Gerlach, that is best - as it is a small post-office (and may easily have exhausted its stocks of international stamps by the time you get there), and is only open part-time hours.
Make-up postage solutions can be found on the current postage rates page - be aware that these solutions will seriously eat into your writing space on a postcard (upper right-hand corner, flowing left) if you use them. Being prepared is best, order ahead. Second best option is to buy a pile of domestic stamps, and come trade with posties.
Here's some helpful information on the current postage rates, what international stamps look like (hint: print this one out), what recent postcard stamps look like (ie: stamps you'll likely run into). Why should you care? Because it's easy to make mistakes when you aren't aware of look-a-likes and other problems.
We have a list of USPS resources, if you want to learn more about the mail.
