I got an email from them asking what I thought of a book. Now the thing is I didn't buy the book but may have looked at it when I was browsing. I wasn't logged in at the time and have actually never logged in on my IPad! Has this happened to anyone else?
Yes they are spying on you, as is most of the rest of the internet.
At Christmas someone on here linked a picture of a doll they wanted to buy for their daughter and I looked at it. That doll stalked me from here to Facebook to Amazon to eBay to the ads at the side of my email inbox and god knows where else.
