They might send me a coupon to sway me to buy the item. Oh dear.They will buy data from other retailers, they share data. Its in the terms and conditions of being a member. CCTV will tell them when you are lingering, looking at products considering a purchase. They can then send you a coupon to try and sway you into buying the item. We are all put into marketing brackets so they can target you to spend more with them. CCTV also has facial recognition so you don't even need to be a customer or a card holder.
