I'd remove all the marvel and Lego products. It's really not worth maybe getting sued one day for copyright issues.
Overall your website is pretty good. I love your footer menu. One of the best I've seen in ages. Keep up the good work.
No dramas. The only way to really get around copyright is to buy the products from a licensed wholesaler in your home country or buy them from a shop and resell them assuming they're aloud to sell them also.
You could use a app called Spreadr and sell Amazon products and get a affiliate commission for each sale if you really did want to sell Marvel and Lego products.
Hope that helped a little
I did a video on the apps I love using below. Hope that helps
