Add to cart button
I installed the site locally to see some features. after some test I noticed that sometimes (not always) when I click the "buy" button on the page of the single product comes out a message that makes it clear to those who navigate the page that the product has been loaded into the cart.

This is essential.
Otherwise you need to find a way to link the "buy" button directly to the cart. How the site currently works is not clear. When the user clicks "Buy" nothing happens and this for an e-commerce site is deleterious.
Obviously there is an update of the number of products in the cart, but this is not enough.
Please settle the situation. Or make sure that the message that should appear is working properly or you link the button to the cart. At present, e-commerce is useless.
