Be my bogof Valentine

Three delightful letters in the Daily Telegraph on the subject of 'bogof' Valentines (whatever they are)

Alan Bennett of Carterton Oxfordshire (the AB?, shurely not?) was

"sure my wife will take up Tesco's 3-for-1 card offer: one to send to me, one for her friend to send top me while she waits to see if I acknowledge it (No), and one to send to herself to see if I get jealous (No)"

Gordon Lamb of Newcastle upon Tyne:

"ASDA has offered cards 'To My Wonderful Wife' at £2 or three for £5"

Malcolm Allen of Southampton

"was offered two for the price of one when buying a bereavement card."
