I was in Asda Govan (Glasgow) last night and they had 2 packs of Birds Eye 10 Omega 3 Fish Fingers for £2 (normally £1.79 each). Anyway when I got home I realised that I had a multi-buy saving of £3.56 showing which means I paid 2p for 2 pack of Fish Fingers. Isn't showing online but was in the special offers freezers at the end of the aisle. Think someone has programmed the system as 2 for 2p rather than £2.
My receipt shows
10 Omega FF @ £1.79 x 2
Kids T Time 2 for £2 535L - £3.56
Don't know if this is local or nationwide.
