At Marks & Spencer, 400g packs of frozen Wild Atlantic/Canadian Raw Scallops are on offer @ 2 packs for £10. They are the larger scallops, not the tiny ones. Great offer as each 400g pack is £8.00.
I know this offer won't appeal to everyone, but if you like them if's a good deal. (Other supermarkets packs are usually 200g and cost about £4 - £5). As they are an expensive item I only buy them when on offer!
Also included in the '2 for £10' offer are various packs of prawns: Extra large Greenland 400g, Honduran King prawns (not sure of weight), Fruits de Mer and other packs of fish. The prawns & fish items range between £5 and £6 each, so not much of a saving.
Not sure how long this offer runs for - didn't have my reading glasses to read the minute print!
UPDATE 14th FEB. - Offer runs until 2nd March, according to the red shelf-edge label.
