From an easy to use website to the delivery it’s been brilliant.
As an older person ordering an electrical item doesn’t come easy so ordering 2 items on 2 different occasions from Lifestyle Home Appliances has been amazing, good old fashioned service and the delivery men both times were always very pleasant and helpful, always good communication and well within delivery time slot ! WELL DONE 👏
