Baileys Original / Coffee / Mint £9 at Co-op
70ml - aound £13.50 at Asda, Tescoa and Sainsburys
1 litre £15 at Asda, £16 in Sainsburys and £19 in Tesco. £10 in Morrisons - but as not everyone is near one, i thought this was a good deal for those that aren't.
So this seems the best price at the moment if you aren't near Morrisons.
