On one of the web sites i look at there is a seed swap forum. As it suggests people can swap unwanted seed with other people's unwanted seeds.
Received some green beans 'cobra' and tomatoes 'gardeners delight', 'moneymaker', 'roma vf'
So far i have sent out some mini peppers, fennel, garlic chives, aubergene
Hoping to get some grass seeds and peas in return
Also got some seeds from thompson and morgan too. Special offer 5 packs for £1.99. Got cauliflower 'all year round', tomato 'gardeners delight', lettuce 'ultimate mixed', brussel sprouts 'falstaff' and peppers 'summer salad mixed'. Some i will use and some i will swap. Hoping for some celeriac or lovage. I wanted to try celery this year but by all accounts very difficult to grow!
