The very first benefit is saving cash on tax obligations. If the merchant you are buying from does not have a local visibility in your state you do not need to pay taxes. For example, Amazon.com bills sales tax for orders shipped to the states of Kansas, Kentucky, North Dakota, & Washington. If you do not live in those states you can purchase a product from Amazon and also save your loan on sales tax obligations. When you choose to get a product from an online merchant, ensure you review the fine print about where they have a regional visibility.
