Its my first deal post and I am working from memory here so please be gentle (the ad is in todays papers).
I think the offer runs from today to the 29th Oct.
Samsung D900i - £79.99 from £99.99
Sony Ericsson W810i - £59.99 from £79.99
Nokia 7373 - £59.99 from £79.99
Nokia 5300 - £49.99 from £69.99
The W810i is a fantastic price.
These prices also seem to be available on the O2 website as well as high street stores although the ad in the paper didn't point this out.
