Tesco's Lighter choices also have points on their packaging.
Also, they have the WW muffins for just £1 a pack of 4 at the moment.
I also find Iceland are really good on the WW meals - usually only £1 for meals and desserts (although it tends to be offers, like £1.25 or 3 for £3, but I find them a bargain as I love the meals & desserts).
If you're into ready meals, my favourites are the tomato & basil chicken, chicken hotpot, spaghetti bolgonese, tagliatelle bolognese, beef ravioli and salmon & broccoli melt.
That's a lot of favourites, I know, but they're all just so nice.
I've also found that tesco & morrisons (not sure about asda), but their frozen, own brand ready meals are cheap, and usually quite decent on points values. They don't have the points on them, you have to work them out, but if you have a smartphone, I have an iPhone, not entirely sure about others, but I downloaded a free calculator app and use that to work out points on stuff all the time.
Good luck with your weight loss journey =)
