I recently purchased a new phone directly from Nokia, as they offered a Trade in service, but the whole offer is a scam, and the 3rd party company they use will have you send your phone to wrong places, and not cover the costs of delivery. All in all, the phone isn't bad, it's the second one I bought from them, but it was more expensive than without trade in, as I had to pay for a tracked postage and in the end they didn't honour trade in. I don't think I will be buying from Nokia again.
