Your website "Title" is all messed up.
When did you start the BB.. Give it time.
Personally I don't like the domain name.
I won't put a value on it yet. But you should fix your title asap.
I am familiar with the largest money saving site in England, which happens to be MoneySavingExpert.com and it is 58th in England, and 1585th in the world according to Alexa in terms of traffic with an almost unbeatable footprint. EVERYONE knows about it, and they also know EXACTLY who owns it even if they do not have internet.
If you try to compete in England you will be seen as a cheap copy trying to cash in and that will not be good.
Your best bet is to try to develop things away from that area (somewhere far away) and actually do something with the domain for a couple of years, point out savings, find cheaper items and blog about it, find giveaways (they do exist) and then sell for a multiple of monthly revenues.
Try Australia, New Zealand or America...they are screaming out for a site like this.
This domain has no value as I can see, it lacks any real focus, and only developing in some way can bring that
