Bought a box of these yesterday, full price of 88p. Other burgers in the range eg. with cheese, were at least a couple of quid. On trying the burger, was suprised to find it was a really good grainy quality. Went back today and bought the other nine boxes in the freezer. Not available online and may be store specific, but was not labeled as a promotion which is why I think it may be a mis-price.
