need suggestions: organic, gfcfsf food suppliers in London area

[Guest guest]

I am hoping to improve my son's diet and need a little help...although I use

organic products as often as possible, I find that my local selection is rather

limited (Waitrose, Sainsburys mainly), especially considering the need for a

gfcfsf diet. We haven't lived here too long, so I would appreciate any

suggestions for organic and diet-friendly food shops/suppliers...that includes

online shops.

Thanks in advance for any suggestions!
