Sir; That's the very last time I ever attempt shopping over the internet. In the latest farrago at Tesco, item after item was out of stock and either replaced with something more expensive or with nothing. This is typical: I asked for two six-packs of lamb grillsteaks and I get one pack of four beefburgers. And I paid £5 for the privilege! Fiona Gordon Durrington, West Sussex {{LETTERS }}
