How does the enhanced trade in work with the mobiles website? £250 on top of the £160 offer price? Its not very clear.
I've not used this before but as far as I can tell, it's all tied to your new phone purchase.
You order a new Pixel now and then send your old phone in for trade in. The £160 is dependent on the phone condition and may be negotiated down but the £250 is a bonus on top linked to your order number. If they end up offering you £100 for your old phone and you accept, they bank transfer you £350.
