Amazon have this toothbrush up for £84.27, but they have an offer on on thier new Health and Beauty Store for £15 off a £75 spend.
So this comes in at £69.27 for the top of the range Triumph toothbrush with the wireless smart guide module.
For reference I just had mine delivered and its a Triumph 9900 brush inside with the guide and features four different modes of brushing along with a couple of heads too :)
FYI the 9500 model retails for the same price on Amazon too :)
And before anyone says £XX on a toothbrush, you must be mad, I just got to the end of lfe on my old brush, 4 years old, gone through numerous heads but I picked them up cheap ages ago anyway - it hasn't cost me much more over its lifetime than a normal brush would have :)
