Most estate sales run for 3 days and normally start on Friday. Friday, Saturday, and Sunday are the most popular days to have an estate sale. The weekend is most effective for estate sales for obvious reasons (Many People Are Off Work and School). Some sales run on Thursdays and On Mondays in addition to the weekend days in order to help move larger accumulations and target antique dealers and those who work on weekends. Mondays are sometimes clean-out and pick-up days also.
Most estate sale companies run a 3 day tiered discount. Friday Full Price, Sat. 25% Off, Sunday 50% Off. This is to ensure items sale for top dollar and increases sales a the sale comes to an end. Sunday is a very busy day for estate sales since items are 50% off or better that day.
