Fotango are a new online company who offer allow you to process your films through the post. All you have to do is sign up and they send you a freepost envelope in which you send your film in and pay the appropiate price and send it off. If you don't want to pay for a set of prints, you can have the pictures uploaded onto a secure area on their web site, which only you can enter.
A bonus when signing up, is that you can get a free film or free processing if you get the correct url of a sponser. These can be found on freebie sites, luckily.
Overall, a great way to get cheap photos.
