Although this software is only available for Windows or Mac, someone who is looking for a good editing software, might want to look into this limited time offer.
My cousin has used the software and liked it enough, to buy it, at this price (i believe it is a British product and you don't get charges any tax).
There is a free trial, so you can take a quick tour of the software and then purchase it, before the offer is withdrawn.

Interesting. I had never heard of them before. Good to know there are other options out there besides Photoshop even if it's not for Linux.
