Instore Tesco currently have 3 for 2 on all boxed glasses.
Quite a selection available:
John Smiths (Pint)
Old Speckled Hen (Pint)
a few others as well but cant remember thier names!
These are the really good quality thick glasses that you would expect to find in a pub- Not like some of the thin cheap ones you come across in some shops.
Great for filling up the cupboard or even fathers day on Sunday!
