If you are thinking about purchasing an appliance in NC, this weekend could be a good one to do so. November 2nd-4th is North Carolina's Energy Star sales tax holiday. Some items that qualify are washers, refrigerators and freezers, air conditioners, heat pumps, ceiling fans, dehumidifiers and programmable thermostats. You need to pay for and request immediate delivery of the product. The NC state sales tax rates can be anywhere from 6.75% to 7.25%. So on a $500 appliance you could save around $35. It may not seem like a lot, but these things add up and if you are in the market to buy one this weekend would be the time to do so.
