They don't offer product themselves - but do provide you with easy access to loads of furniture and home decorating stuff from a bunch of different retailers, as well as expert advice and tools to help you choose that paint colour, toilet seat, sofa or fridge. Yeah, fridge. It's Brit stores only for now - but the US should be up next.
There's even a mydeco Web deco magazine and social network for interior designers and home deco fanatics. Nice if ya have the time! For the rest of us it could provide a nifty slouch potato mechanism for getting your home sorted online and freeing up time for more football/clothes shopping. Yah.
