I don't want to disappoint you, but actually there are 7 SKU's on the website. That is because two products come into two different sizes (thus having a separate SKU for each size). [A stock-keeping unit (SKU) is a scannable bar code.] Namely, the LASAGNA comes in both the "Two-serving size (600g)" size and the "Full Size (5-6 servings 1.42kg)"; the SHEPHERD'S PIE also comes in the "Two-serving size (600g)" size and the "Full Size (5-6 servings 1.42kg)" size.
