I recall reading about a scam, that went something like this.
You buy something online, and it seems to be a reasonable price. Maybe 40% less than the listed price. So instead of paying $1000, you pay $600. Nice, you think. You scored a great bargain. You buy it, and the product gets shipped to you, all new and everything.
Fantastic! You think. You scored a great deal.
But behind the scenes, what happened is that seller bought it with a stolen credit card, at normal prices. Then sold it to you at the cheaper price. He pockets the $600. The vendor gets paid the $1000. But the guy whose stolen credit card got used, now gets hit with a mysterious $1000 bill. Poor guy. Now he has to file a police report, and claim that he didn’t make this fraudulent purchase, and turn his life upside down for a few months.
Sometimes, it’s best to not trust online sales.
