Macy’s is once again keeping some of its stores across the country open 24 hours a day in a bid to squeeze every last bit of holiday cash out of shoppers.

Starting Friday at 7 a.m., 37 Macy’s stores will keep the doors open ’round-the-clock through 6 p.m. Christmas Eve.

Three of Macy’s D.C.-area stores – in Columbia, Md., Tysons Corner and Pentagon City – will keep their doors open nonstop between Friday morning and Christmas Eve, a total of 107 hours.

Macy’s has a total of eight stores in the D.C. area.

Most other Macy’s stores across the country will have extended hours, open until 2 a.m. through Dec. 23.
