Tesco have started its latest advertisement ploy by making people believe they are getting a better deal and cheaper prices by holding a clubcard or data card has i like to call them and they have victimized people who dont have a clubcard with price hikes i.e one price for the people who give tesco there data via the clubcard and one for the ones who dont sign up and give thier data basically daylight robbery for people who like to keep thier data private.The only problem ive seen through research is that the clubcard customer are not getting products cheaper but getting them at the same price has asda and all the other supermarkets take a packet of pringles club card customers can pay £1.50 for the snack yet people who dont want to sign up with tesco pay £2.50 now thats daylight robbery and also conning the loyal clubcard owners into believing that they are getting a cheaper deal when infact the are not.Your data is very valuable and they use this in more ways than one PLEASE BE CAREFULL
