There is a myriad of online stores out there, and it is impossible for one to compare the different toroidal transformer as well as their prices since not all websites offer them. Online shoppers often turn to reviews and customer feedback for help, but even these are unreliable sources. Sometimes people post negative reviews just to be spiteful or angry.

The lack of insightful information online forces shoppers to rely on the information they find elsewhere, but this can lead to misinformation and incorrect purchase decisions.

Consumers can save themselves from these potential risks by turning to an AI-powered shopping assistant that provides tailored product suggestions based on their preferences.

But Amazon made the whole process easy and effortless.

  • They worry about their personal information being stolen;
  • They question the reliability of the website;
  • Its security features and whether or not their credit card details will be safe
  • The quality of products sold by third parties might not be as good
  • There’s no instant gratification with online purchases;
