If you are a retailer selling for normal market price you do not need to fear much. However especially those big companies that spend a lot on marketing themselves as beeing low price might be defaced as what they are: Not cheap at all. Because usually those big companies advertising products at 30% or 50% of, are comparing their prices not to the market price but to the recommended retail price of the manufacturer. And even if you make a bargain on something like a digital cable receiver this will be swallowed by the price you pay for the HDMI cable.
When I bought a laundry dryer I checked the price at the local "cheap" electronic store belonging to a big chain and local small B&Ms. The prices at the small B&M were nearly always lower.
