Most people know by now but you can combine the Boots meal deal with BOGOF 500ml refreshments (currently sprite, fanta, ribena and Dr.Pepper) (£1.10 each) but they are also currently including the big bag of Cadburys Clusters in the deal (normally £1.80).
So for £2.99 you get
Wrap/Sandwich/Salad (up to £2.75ish)
2 bottles of Juice (£1.10 each)
saving over £3.00
