Trying to remember a website...

[Masterdog]

Hope somebody can help me with this one - I'm trying to remember a website I frequented a few months ago. It was dedicated to finding deals on mobile phones from various online shops, mostly of the cashback variety. I think it was a forum rather than a webpage however. I also think it may have had the word 'box' in the url, but not sure about that.
Very vague I know, but thanks for any help.

Those are both good sites, better than the one I remember tbh. Was more an annoying - 'oh, what was that site' kind of thing. Thanks for the links tho.
Anyone had much experience with these rebate kind of companies?
