*************************************

Just a heads up that Tesco Clubcard Boost starts the 16th May and runs until the 26th June

If you need to earn some more points you have until the 5th May which is the cut off date for the current collection period. Easiest way to get some points is to convert £50 cashback from Topcashback into 5000 Clubcard points (max is 5000 points per year) - worth £100 in the double up
