I use the Knorr ones. But only because I got them cheap off AF. I love AF but I'm a bit of a hoarder and like a bargain. They are bad for your cupboard space and can be a bit frustrating as they don't have the ingredients of things so you have to google like crazy particularly on obscure and foreign goodies. I bought some pickled cabbage from them never suspecting it would have anything untoward in it but it had lactose as an ingredient! It could have been the synthetic one I suppose like they use in olives but I was a bit miffed.
But right now they have tofu for 50p, I think there is still some rice milk, the worcester sauce is vegan, and AFAIK they are still doing free delivery for new customers. But at my house ... OK, its confession time ... my husband is getting so worried about the full kitchen that yesterday's order came while he was out and I haven't told him about it, just got the soya milk (sorry - I had the last of it) hidden under the settee.
They even have vegan chocolate sometimes

I got a large batch of the choices caramels for 75p each. But personally there are some things like grain based products I wouldn't buy much of when out of date. They had a load of organic Crazy Jack's in a while back that was VERY out of date, I got some cous cous to try and you could taste it was too old. I've had flour I've stored too long and pasta too so I would't buy that unless it was only about 6 months past its bb date.
As far as I know, they are still doing free p&P for new customers but my last two orders have only been £3 for 50 kilos, previously its been £5 something which isn't bad considering supermarket delivery charges or petrol or buses.
