With orders of $25 or more, Amazon offers the La Costena Refried Black Beans 20.5-oz. Tin 12-Pack for $4.99 with free shipping. That's tied with last week's mention and $11 less than what you'd expect to pay in your local store.

Note: This item is part of Amazon's "Add-on program" and can only be purchased with an order of $25 or more. Also, it usually ships within one to two months.
