For Prime members only, Amazon offers the Chicken of the Sea Premium Skinless & Boneless Pink Salmon 2.5-oz. 12-Pack for $10.95. Add to cart via Subscribe & Save to drop it to $10.40. With free shipping, that's around $4 under what you'd pay in local stores, although we saw it for $2 less three weeks ago.
Note: Be sure to cancel your subscription once your order ships to avoid being billed for further shipments.
