Walmart offers the Hanes Women's Long Sleeve V-Neck T-Shirt in six colors (White pictured) for $3.50. Choose in-store pickup to dodge the $5.97 shipping fee. That's the lowest price we could find by a buck. They come in sizes S to XXL, although not in all size/color combinations.
GearXS via eBay offers the Steve Madden Women's Fleece-Lined Leggings in Black for $4.99 with free shipping. That's tied with our mention from a week ago and the lowest total price we could find by $5. They're available in sizes S to L.
