I've used to buy Kings seeds. good quality and germination, but over the past few years I've been buying at Wilko, Lidl, and Aldi. Have to say that the germination isn't always as good and the range limited. This year I bought some seeds from Moores (mail order from Langham, nr Colchester). Excellent seeds, although you have to buy largish packs which don't cost much more (per seed) than Wilko but may mean you have a lot left over
