Was looking for a new casserole dish as someone broke the lid of one of mine. This is oven,microwave, dishwasher and freezer proof. Had two separate piles of these in Chelmsford. All scanned at £2, although the price edge of one lot still marked as £4 . Bar code 5 010251573449. This is not online, it is the Morrisons own brand one, not Pyrex.
