4. Be careful with bargains

Every time you search for purchases on the Internet, you need to be careful with websites that you do not understand, have no relationship, have no trust or you have not known anywhere.

Links of this type will often send users to websites that contain forms that require users to fill in information about the card's owner name, number, expiration date and CVV number. After the user provides all of the above information, they will not be able to do anything but only get an error page along with instructions they send money by mail. But in fact they lost their ownership of their payment card, losing their money.

That same scam but now phishing - or the way online scammers falsify reputable companies send emails to customers with content that contains a link where they must also enter The same information as mentioned above. The measure has completely changed.

So users should always be cautious so look for reliable and well-known online shopping websites. Be careful with offers that offer discounts that are too good.
