Whenever I buy anything I always research it on the web first. Not just the specs, reviews and what to look for, but people's actual experiences with specific products. I think skepticism is a great tool for consumerism and could be a great way of popularising the subject. It is an area where people could see a practical benefit to skepticism and that it is not 'disbelieving things', which is the popular image.

I'm sure I could think of hundreds of more interesting things to so with £3.5 - 5K rather than getting a wooden floor!
