Tesco messed up my order today. Forgot to send around half the fridge stuff. They were great about it and agreed to send the missing stuff today. It's just arrived. Except they've sent all the fridge stuff, not just what was missing. We tried to give it back but thedelivery man said we could keep it for the inconvenience. Most of the duplicated can go into the fridge to use later in the week, or into the freezer for another time. I now have two extra packs of sea bass fillets and I'm not sure about freezing them. I don't usually freeze fish, but I really can't use two lots before the use by date. Will they freeze successfully for a week or will they spoil?
