Quite a lot of seeds £1 a packet including gladiator parsnips.
P&P very reasonable at 95p

I think I am right in saying they are the same company as Mr Fothergills. Many of the pictures are the same.
They have free p&p this weekend. Quote D7FEB at checkout.
Useful if you still need to order seed potatoes or onion sets :)
I have gone off DTB in the last couple of years as they practice what I think to be a unfair sales techniques and that is the quantity of seeds in the packet........this has dropped from what it once was and now I find when you price the packet in 'cost per seed' terms they are one of the most expensive around.
Having said that if you only want a few seeds and you don't want to spend a lot of money then this option might be OK
