Sorry not football related!!
Might not come to anything but if you set yourself up with an account at tesco.com and click into the your clubcard section pop your clubcard number in it will give you list of unused club card vouchers. You might have a suprise. I always thought that i always used mine up but i had £23 unused!! Members of my family are finding £54, £30 and £19. These can be spent on line!!
