anybody got any recomendations on where to purchase from as i dont want to pay £100 and dont want to take a chance paying £40 and they dont even come

single-seed-centre.com

herbies
attitude

sea of seeds is much better, dont have to spend XX to get XX free.

White widow from seedsman is only about £40

I use attitude seeds and sannies seeds.

Go with Sannies seeds, they have less variety but in the end you will have the best final product with no risks and at the most fair prices.
