Was looking to buy some tuna steaks the other day and noticed that Tescos frozen steaks have been priced at 10p online (not sure about instore cost). This has got to be a pricing error so if you like tuna grab some before they realise! The same product costs £2.59 at Sainsburys.
Oh and before anyone asks I did order some myself which were delivered today and I was definately only charged 10p. Bargain!!
