Found 6th Dec 2012
It says £1.99 3 for 2 on the website however in the Metro store I've just been to (Torquay) the label said 99p 3 for 2 and they scanned at that price too. So don't know wether its store specific or maybe a deal just in Metro stores? The shelf label was a normal yellow one like any other offer and said it runs until the 11th December. These bottles normally cost £1.65+ each.
