Selling data

I usually walk to shop at Morrisons but it was time to do a big stock up shop so we gave Tesco a try. I have no loyalty to any supermarket but I’m glad I bothered to download the club card app as it got me £19.87 off my bill. Not overly happy about selling my data so they can spam my email account, but not willing to pay to avoid it!
By the time I’d filled the van with fuel I was £250 down…. That inflation thing is real!
