If you have bought them recently, they are the most unlikely things to buy in the near future.
I was actually surprised a few days ago when I have seen for the first time in many years a personalized ad that was useful. When I visited an on-line shop, I was greeted with a message that a product at which I have looked during a previous visit, but which I have not bought, has a 20% price reduction, and at the new price I was indeed interested to buy it.
This kind of notification, about a price reduction, makes sense, but ads for products to which I have looked previously and nothing has changed about them do not achieve any useful purpose. If I bought them I have no need to buy them again, if I did not buy them, this means that I decided that I do not need or want them, so I will not buy them regardless if I see ads for them.
