At Sears, order today (December 22) via free in-store pickup to get items in time for Christmas. Of particular note, get up to 60% off select men's, women's, and kids' coats and sleepwear. Even better, coupon code "GREATGIFTS" chops an extra 15% off. That's the best discount we've seen on sleepwear from Sears this year.

A best bet is the Hanes Men's Plaid Flannel Pajamas in four colors (Black/Grey Plaid pictured) for $19.99. Choose in-store pickup both to get it in time for Christmas and to avoid the $5.75 shipping fee. They come in sizes S to XXL, although not in all size/color combinations.
