"We understand they feel pressure to find the best gifts at an incredible value, and that's what we will deliver. From opening our stores at 12 a.m. the day after Thanksgiving -- our earliest opening ever -- to offering deeper savings opportunities throughout the holidays, we are making shopping easy and even more convenient this holiday season." The mid-priced department store plans to remain open for 24 hours the day after Thanksgiving. Online shoppers can also start making purchases with early bird specials on Thanksgiving Day.
