I get mine with Tesco vouchers and it is cheaper than the direct subs. Worth a try if you collect Clubcard points. I have done it for several years now and you don't have the bother of being auto. locked in a sub. with GW.
I have made scrap books with items i think i will need to read again, usually how to prune things i always forget how to. I still have brambles on my allotment which i have had for 5 years. Have dug them out , hacked at them and put weed killer on them and they still keep growing. They do have the sweetest blackberries. I have a feeling they are indestrucktable ( not sure i have spelt that right).
