As my boss put it, “Gina went insane” at the 600 N. Michigan Ave. Linens ‘n Things liquidation sale over lunch. I came hobbling back to the office with two huge bags full of Nate Berkus linen window panels and a bed skirt. According to my receipt, I saved $350. All sales are final, but if you’re willing to commit on the spot, you’ll be very happy with the deals.
