I recently bought a TV cabinet online without seeing it first. The simple fact was that I was able search a lot of retailers online, and then could make a more informed decision than trying just a few shops on the high street. And the price was better!
I also bought 2 armchairs recently, searched online, found some, went to look at them in the shop, carried on shopping to see if the high street had anything else, and then came home, bottle of beer, and ordered them from my front room - perfect.
