Use this promo code and you get 4 GB of extra free space (valid for two years I think):

2012

And some older 1 GB promo codes you probably already know:

SKYFISH-IS-COOL
CONNECT-WITH-SUPPORT

Don’t know what Wuala is? Most of you are probably familiar with Dropbox, a popular online file storage service. Wuala is one of its competitors, and in my opinion the best out there considering the features it provides.

If you want to get an account and start off with 3 GB, you can use my invite code when signing up ;)
