Instructions:Shopped online at tesco today for the first time and remembered seeing something about discount codes before.Found these online -
XXBOT7 - £5 OFF £50 MINIMUM SPEND
GR3FWY - 750 FREE CLUBCARD POINTS
XX-CRDJ - £5 OFF £50 MINIMUM SPEND
XX-RXF7 - £5 OFF £50 MINIMUM SPEND
I only tried the first two and they both worked.Got £5 off and £7.50 in clubcard points.
You can only use one code starting XX in each transaction.
First post, hope it helps
