Product Cost: $4.17 Acquired at: Waitrose Created by: Waitrose Partners The Waitrose package with roasted pepper and halloumi is another dubious item on our list. The customer thought there would be one sandwich when she purchased the bundle. But what she actually received were two small sandwiches: one with halloumi, a sort of brined cheese that is sometimes used in place of meat since it is simple to cook and grill, and another with roasted pepper.
