pub advertising one price selling another

[filthiestfis]

If a pub advertises 99p for a pint of bitter at the door (sign posted by the entrance window with several beer prices) but then charges £1.50 or whatever above what is being advertised by the door for it, is this legal?

I'd love to pay £1.50 for a pint ... just had a couple @ £3.20 a pint

[ummmm]

£1.49 for a pint of Stella in witherspoons....(sp)

Unfortunately it is perfectly legal. Obviously not good business practice, but as any first year law undergraduate will tell you, an advertisement at a particular price does not constitute an offer by which acceptance forms a binding contract. You have the opportunity to decline the offer at the new price.
