O2 are selling their cocoon instore at a price of £59.99 for this week only apparently.
If you trade in an old phone with a battery and charger they'll knock TWENTY off the price.
I'm downgrading but I fell for the Cocoon as soon as I saw it :( and with 2gb onboard memory it's cheaper than buying an mp3 player too :)
There may be other phones on special offer too, ring your store to find out :)
After this week it apparently goes back up to 79.99. I'm not entirely sure when the offer finishes and I can't get back through to my store to check - apologies!
Don't forget to tell them you're already an 02 customer if you are cos you get some more off it!
