Yes, they are J52 and sometimes they seem to be deliberately confusing.
They do a lot of Mix and Match 3 for 2 type offers - but you have to be absolutely sure you have picked up the right kind of tomatoes-on-the-vine and the right kind of green beans and the right kind of potatoes, otherwise you risk getting to the check out and finding the stuff you've picked doesn't actually qualify for the offer.
Quite often they have two or more 3 for the price of 2's placed right next to each other on the shelves and it's very easy to pick two things from one offer and one thing from a separate offer, also disqualifying you, so you have to check that out as well.
Then you have to work out whether you're actually going to be able to use the stuff up or freeze it or have time to cook it and freeze it and what else you need to make a meal out of it, deal with the offers they have on those items, then work out whether you wouldn't in fact have been better off just picking out what you went in for in the first place.........
