Too Good To Be True

What is something that is too good to be true?
A explanation that is both definitive and exhaustive would be impossible.
Instead, I will provide at least one example of something to look for.
Early on Christmas of 2024, Bestbuy had a 50 inch television on sale online for $120 plus tax delivered.
If you were monitoring online shopping forums that mentioned that sale at the time, you would have noticed some skepticism as to whether the orders would be fulfilled.
In the end, some people who ordered too late may have had their orders cancelled, but it was not a scam.
However, if you were to see a similar offer by a website which you were not absolutely sure is legitimate retailer, there is a strong probability that it is a scam.
