Brilliant app - in case it is new to you, you buy credits, take a photo on holiday, write a postcard message and send it to any address - it is posted in the UK, turns up a few days later and your mum wonders how on Earth they sell postcards of you on a camel over in Morocco. Cheap for post card and delivery at £1.49 but flash sale today is seriously cheap - I just bought 25 for £20.

And of course if you want to be in the postcard, use a photo with you in. The postcard quality is excellent.
For iphone/ipad, android, windows phone & laptop/pc.
