Facebook always showing me ADS of things I bought

Yesterday the shower head broke, so I went out to buy a new one and bought a gas pressure regulator with it Today when I was scrolling on Facebook, I found an AD for the same item and this is not the first time Facebook has shown ads for something I purchased I was shocked because I didn't take my phone with me to the store and didn't search for those items on the internet or even talk about them …
