Tottenham Court Road
Take a left at the east end of Oxford Street and you will find yourself at the electrical retailing centre of London.
From hi-fi's, mobiles, laptops and cameras to LCD, HDD, Blu-ray and gigantic home cinema systems, every conceivable electronic gadget or gizmo can be found here in abundance. You can even buy CCTV gear, so that you can make sure your gigantic home cinema systems are safely guarded when you're away on holiday.
If you do decide to make a purchase be sure to haggle - you might not always get a discount but competition is fierce and you won't be being rude by making an offer. Also, be sure to make certain that the item will work in your home country before you leave the store and don't just take their word for it.
As you head north, the theme of shops moves steadily into housewares and furniture.
