This shop opened about six months or so ago, not that far from me in Rawai, Phuket, and have now started doing deliveries throughout Thailand. If you email them (FoodForForeigners@hotmail.com), they will send you a product/price list. Absolutely nothing to do with me, I just know that some on the forum do not have easy access to Western orientated supermarkets such as Villa Market etc. FFF's range of products is extensive, though virtually wholly British origin. Everything from Tetley tea bags to Rowntree Fruit Gums, Fray Bentos Steak and Kidney Puddings to Mushy Peas.
Some photos that I took a while back:
