Major appliance brands unveil their newest models in September, for consumers to see ahead of the holiday season. Older models of dishwashers, ovens and refrigerators drop in price to make room for the newer versions. There’s nothing wrong with buying the previous models, and it may actually be smarter. Newer models may have glitches that need to be worked out, while older ones have already had their issues resolved. Check out stores such as Best Buy and Appliances Connection to find low prices.
