Cuprinol sprayable showing as 3 for 2 at Tesco but the deal is actually 2 for 1.
So buy 2 for £13.99.
Also includes the SPRAYER!
I bought 1 sprayer and 5 cuprinols for £52 (should have been a total of £95).
I also got 500 extra clubcard points giving a total of 604 points which I convert to £24 off restaurant food!
The extra points has now expired but now free delivery if you spend £50 and you may also get 20% off gardening products but not sure about this
You may also be able to use quidco.
