I wouldn't touch Simply Electronics with a bargepole of any length. Dealt with them once, which was enough for my lifetime.....
Misleading advertising (most of their stock is grey import and will arrive from overseas, leaving you with a possible customs bill)
Impossible-to-contact customer support (they ONLY responded to me upon threat of legal action, and even then on the last of seven days they'd been given)
In the event of your being eligible for a refund, you may have to wait until a UK court orders them to pay.
These are my personal experiences, others may have had better luck in dealing with them.

Youth and experience are no match for age and treachery.
