No seacliff. It's an independent pharamacy and I paid cash. I can only assume it was just a fantastic coincidence else paranoia creeps in and one starts to wonder if stores have installed bag tracking tech!
Which makes me laugh in a way. Any tech trying to analyse the content of my (hand)bag for example (and those of many other women I imagine) would crash immediately confused by all the stuff that lurks in there. Six lipsticks, a leaky pen, old train tickets, twopence, something that could be Ibuprofen or a peppermint, a pine cone, the spectacle cleaning cloth that's been missing for months, a plastic bag of dried-up wet wipes.
I've experienced the things other posters have mentioned. I closed my FB account because (amongst other reasons) I was tired or them tracking my browser history. One brief visit to a retailer site resulted in persistent FB ads for the same company.
