Both Iceland and another store called Farmfoods sell frozen foods.
There are some items that one sells that the other doesn’t so it can mean “shopping around” a bit and I am considering a stand alone freezer because they both have bargains to stock up on.
Things like frozen fruits, natural fish, slightly cheaper butters and “nostalgic” stuff for me such as Brains faggots and sliced lambs liver - which I get a fancy for every now and then ..(not together)?
So, great for batch baking puddings and fish pies etc.
As well as plenty of vegetable choices, and meats.
They both have salad and fresh fruit and veg plus popular tinned veg, but also sell good bargains on detergents and loo/kitchen roll.
