As one of its daily deals, That Daily Deal offers this Reusable Toaster Sandwich Bag for free with free shipping (one bag per household limit, 67 cents per bag after). That's tied with our mention from a week ago and a buck under the best price we could find for a similar bag elsewhere. It measures 7" x 6" and purports to be reusable up to 50 times. Deal ends today.
Note: You must order one bag to get the discount. Ordering two or more bags will charge you for every bag in your order.
