With orders of $25 or more, Amazon offers Prime members the Pyrex Bakeware 4-Quart Oblong Baking Dish, model no. 6001040, for $5.35 with free shipping. (Non-members can spend $49 or more to qualify for free shipping.) That's $4 under last November's mention, which didn't require a $25 purchase, and the lowest total price we could find by $10. It measures 15" x 10" x 2".

Note that this item is part of the Amazon "add-on" program and can only be purchased with an order of $25 or more.
