ONLINE SHOPPING SAFETY TIPS

The Internet has had an enormous impact on the way people shop, do their banking, make investments, plan travel, and even how they pay their taxes. In the vast majority of cases, the experiences have been positive. Online shopping allows you to find items — which are sometimes hard or impossible to find in local stores — and typically get the lowest possible price by comparing prices with a variety of merchants. Yes, there are risks associated with shopping online, but they can be managed. Besides, there are also risks associated with driving to a store to make purchases.

Online banking and investing is another great convenience. With a click of a mouse or a touch of a smartphone, you can transfer money between accounts, pay bills, and make investments.
