20 X 50ml bottles of Bailey's in Original (8) Creme Caramel (4) Mint (4) & Coffee (4).
This is essentially £8.99 for a litre. I went to Asda afterwards and it was £14 on rollback for a bottle of the original stuff.
This was in B&M Bargains in Blackpool (Whitegate Drive branch) so not sure if in the others.
These are great for carrying around where a double will be alot more expensive than 45p! ;-)
