Be careful when ordering in store, they jump on you and follow you around. We made the mistake of taking our children with us, who were getting impatient which then made us rush with signing things. It wasn't until we got home and properly looked we realised they had added insurance at £200 and a cleaning product at £50. If i was ever to order again i would only do it online.
Also when trying to ring up the next day to cancel the insurance they then kept saying there was no one in store who could cancel it for us.
