We came across Abt Electronics, haphazardly, while looking for the best price on a printer on Pricegrabber. What we found were good prices and a variety of appliances from computers to refrigerators, all under the same roof. A traditional "mom and pops" store founded in 1936, Abt Electronics is located in Chicago but serves the entire US through its website.
After reading some of their stellar reviews, we seemed to notice a general trend of real, personable service combined with the convenience of online shopping. This isn't just an online warehouse, but a real store with real people on the other end.
