Blight on my tomatoes!

You've just got to shop around and ignore most of the big name seed shops unless they have a good sale on. Premier Seed Direct sell Losetto, Lizzano and two of the Crush line for 12-13p per seed and Pennard Plants many of the other plants on my list for 13p per seed (with a few at 20p). You can probably get at least 2kg of fruit from one bush tomato like Maskotka and some hybrids will give you even better yields. Organic cherry tomatoes sell at £10+ per kilo in the supermarkets so if one hybrid tomato plant gives you £20 worth of fruit for 13p, that's a pretty good deal!
