So, here's the deal with Red Tree's Sidewalk Sale. It's not really on the sidewalk. But it is a sale. Up to 65% off select jewelry and home accessories as they clean house and make way for fall and holiday merchandise. The sale kicks off Friday at Hampden's First Friday and runs until the 16th. This Friday they'll have a Klezmer house band—Verklempt—and Golden West will provide 70's inspired bites like tater tots and pigs-n-blanket and drinks.
