Great

Easy, fun, and unusual!
But keep in mind that it is more expensive to send cards to europe than it is to the USA; the app supports the latest versions of iOS, so it doesnt work anymore on iphone4.
Great app, as well as its big brother "ink" that enables you to make great personnalised cards (but more expensive than postagram); I recommend it!
