Found this whilst reading about on the TomTom 940.

It seems like it pretty much comes with this £50 Fuel rebate at most places, but Quidco are offering 3% cashback for BT Shop which makes this the cheapest I can find...and you need fuel anyway, so effectively makes this under £330 new

Top of the range Sat Nav...its not overly that much different to the TomTom 930. Some great features including local fuel price updates, local Google search through the TomTom etc.

If anyone knows of these being cheaper elsewhere I'd be interested. Seems about £420-£450 average
