Probably because you searched for boxers. My Ihub page shows ads from Houzz and Wayfarer, because I looked at those websites. What YOU see is what you have shown interest in somewhere on the web.
I have not seen that but I asked my grandson and this is what he said about that:
The reason you see other products on the ihub page is because you went to that page and they track visitors. If you clear your cache and cookies you wont see that anymore. Its internet marketing and every person will see different advertisement on their page depending on what sites they have been to. You will see it on other pages as well. It follows you and constantly targets you to buy
