The nice people at MOO - makers of all things printed and pretty - kindly joined in our millionth card celebration by offering Postcrossing 10 packs of postcards. We will distribute these to the winners of our "a million cards' contest", for 2 lucky users in each of the five categories.

Have you tried MOO postcards?
Each pack of 20 usual sized postcards can be individually personalized with your photos or neat ready-made designs. You can also choose from a variety of back templates, different fonts and colours allowing you to apply your personal stamp to your set of postcards. We use MOO for our postcards too, and we are very happy with the quality of their service!

Additionally, MOO has a couple of promotions running this month:

• When buying postcards packs (and especially for Postcrossing users) you can use the code postmoo on the payment page to receive 10% off any amount/type of postcards you buy.
• When buying stickerbooks, you can get '3 StickerBooks for the price of 2' by using the code moostickersfree when purchasing (just make sure that there are 3 packs selected in the basket, before entering the code).
  Stickerbooks allow you to produce 90 different stickers using your favorite photos or designs, and are perfect for adding that little extra something to your postcards.

You can only use one code for each order (but you are welcome to use them both, as many times as you like) and these two offers end by April 30th.

So, get busy and participate in the contest for a chance to win a free postcard pack!
