I've got one of these myself and they're fantastic.
Cheapest online I could find is £220.
Use FAFS89 to get a further 10% off on top of the 15% off.
You also get a Boots Shapers Active Exercise Punchball and Gloves Set which is worth £25 free.
Unfortunately there's a £4.95 delivery charge due to the size and weight of it, which I've included in the price.
Another £6.34 available in Quidco and 939 in Boots points.
