BUY ONE GET ONE FREE on Dove Beauty Cream Bar (3x4x100g) with the coupon. If you are already a member, you will know that you don't really need the coupon as they automatically scan a discount at the checkout.
At £5.62 (inc VAT) for 24 bars (23p'ish each) , its not a bad deal, especially when prices at the supermarkets are around 50p a bar (unless there are special deals on).
As with all other Costo deals, membership is needed but if you know someone with it, ask them to take you!
They also have Sensodyne Toothpaste (75ml) 6-pack at '2 for £18.80 inc VAT' making each tube £1.57 which might also be a good deal. 12 tubes should keep a family going for a few months.
Its all about wholesale baby!!! lol
