Whoever says that the dollar doesn't buy what it used to, obviously has not shopped JC Penney this quarter. JC Penney ran multiple and often stackable simultaneous promotions through December and early January. Judging by their holiday season sales results, all the efforts paid off in the form of higher top-line numbers. Revenue at stores open at least a year rose 3.7 percent in December, beating the 3.3 percent consensus analysts expectations. Customers who don't normally shop JC Penney came to snatch up some rather amazing deals.
