Long time lurker; first deal posted - be gentle with me :-)
I was looking to buy a TomTom 750 Live but was put off by the £8 / month subscription. This is the service where the TomTom unit has a Vodafone SIM card in it to receive and contribute to the traffic information. It also gives other "Live" services. I had seen that some retailers had offered a 50% discount on an annual subscription. Then I found this - a free 12m subscription if you buy one of the devices within the dates - extract from Ts&Cs below:
# The offer is for a 12 month subscription to TomTom LIVE Services.
# This offer is exclusively for customers of TomTom UK purchasing a new TomTom GO 950 LIVE, TomTom GO 750 LIVE, TomTom GO 550 LIVE, XL LIVE IQ Routes UK & ROI or the XL LIVE IQ Routes Europe, from participating retailers between 18th February 2010 and 6th April 2010 inclusive.
# The 12 month LIVE services offer assumes commencement immediately following the "Out of the Box" LIVE services offer.
Apply by printing out a web form, attaching a photocopy of the receipt and send to TomTom by 6th May 2010 at the latest.
In a way it's a Freebie, but I have categorised it as a Hot Deal since you have to have bought a satnav first.
