E-commerce is one of the most innovative Internet applications, even if it requires a bit of attention as in private life.
For instance, the fact that a website is written in Italian does not necessarily means that it is operated from within the national territory.
In this respect, it can be helpful to use some tools to find out the website's country (hosting location) and the names of the persons in charge, which can also be found for free online (i.e. www.checkdomain.com).
This information is important especially to find out your rights and obligations with respect to your purchases, and in particular your right to return and obtain a refund for products.
