Yes, that's where I shop too and they have a good range - also very helpful and the orders are delivered quickly.
There's very little LC specialist stuff available to buy in the shops anymore and you have to make everything yourself - no bad thing really. I couldn't do without gluten flour, Dreamfields pasta and pancake syrup, all of which are available only online. My other staples include ground almonds, linseeds and coconut and are readily available in supermarkets, thankfully.
