Store is priced in USD, but converts to BTC at checkout. The sticker is $1.49 plus 99 cents US shipping. Shipping is flat rate so you can get a pack of 10 stickers shipped in the US for about .25 BTC (there is a quantity discount as well). These are high quality UV protected vinyl for outdoor use. 3"x10"
I also ship internationally, I email you for the shipping in BTC. http://cryptoanarchy.com/store/index.php?route=product/product&path=59&product_id=56
