Where do I bulk buy basics online?

[Unrulysun]

I'd like to get a big sack of flour, 5kgs of lentils - stuff like that. Hating lugging it back from the shop and want to get strong bread flour cheap in return for buying lots which Ocado/Sainsburys etc won't do.

Approved Food is good for some things, but they are very hit and miss over what they have in...

Not tried it yet but I was recently recommended these SUMA

There is also DOVES FARM who also do Gluten Free stuff.

Thanks for these - will check them out. :)
