There is a myriad of online stores out there, and it is impossible for one to compare the different co2 kit 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.

Why You Trust Amazon?

As they grow increasingly popular, there are some challenges that people face when they try to purchase something on the internet. There are many reasons why people might not trust Amazon as much anymore:

  • 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;
