With Black Friday just a week away, what do shoppers need to know about holiday sales? Richard Lancioni of Temple's Fox School of Business urges consumers to do their research. "The best way to know is to be aware," Lancioni said. "In other words, to know your prices and to be able to compare that to what the list price is. If you know your prices and you can look at the discounts that are being offered by the store, then you’ll know it’s not a scam, that it's real. So buyer beware!"
