Sainsburys currently have Fitbit Charge HR on offer at £90.00 (down from £120.00). Have seen this at two Sainsburys in Essex area but not sure if it's National. Stocks on shelves seem limited so this may be to clear items, might be worth asking if they can order in for you if no stock locally to you. Only seen the black and burgundy / purple colours on the shelves in the two sizes this model comes in (large and small). Has been cheaper elsewhere previously but might be of interest if you are currently looking to buy.
