What % of consumer electronics peurchases made in a bricks and mortar
retailer are first researched on line?

It is only sensible to research online where possible - you can
compare prices and availability for instance. There is the other way
round of course - going to a large retailer with lots of different
models on display - choosing the ones you are interested and then
looking these up on the web in order to get the best deal. As these
methods are a lot easier, less stressful and quicker than trailing
round from show room to showroom, maybe with children in tow, I am
sure that the percentage will constantly rise so it will be very
difficult to give an answer that is true for more than a moment in
time. You are also a lot less likely to have the pressure of buying
warranties you don't want or need.

Your question is about to expire without having been answered, and you
might be disappointed.

A possible reason for that could be your pricing, which might be a bit
low for the type of research requested. Here is a link to guidelines
