The Utah Division of Consumer Protection offers its annual tips to shop safely online.
Use your smartphone wisely • Be certain what apps you install are from legitimate sources. Keep an eye out for fraudulent charges on your phone bill. Never leave your phone unattended.
Don't send cash or wire money • Never send money for an online payment over a wire service such as Western Union. Pay by credit or charge card.
Compare prices • Online scammers will offer ridiculously low, too-good-to-be-true prices. Avoid them.
Research the seller • Confirm the online seller's physical address and phone number if you doubt their existence.
Keep anti-virus software up to date • Sketchy online sites can lead to virus or malware attacks.
Use only secure sites • Do not email financial information like your credit card number. Look for indicators that the retail site you're using has secure measures in place.
Print and save records • Keep evidence of all transactions, including the product description, price, online receipt, and emails in case you need to return a gift after the holidays.
Be aware of their refund policy • Check to see who pays shipping if you have to return an item and if there is a "restocking fee."
Read reviews • Learn more about the retailer and products you want to buy by reading users' or columnists' reviews.
