In Case It Needs Saying, GeForce RTX 4090 Listings For $399 Are Definite Scams
During the recent Amazon Prime Big Day Deals, you'll find a smattering of good prices on PC hardware, even the NVIDIA RTX 4080 was on sale for $989.99. Some users may have seen a $399 RTX 4090, or even a $455 AMD 7900 XTX. GPU sales may be slower this year, but they're not nearly that slow.

Secondly, remember that Amazon has plenty of third party sellers - most of which are honest, but you'll encounter the odd scam still. Remember to check feedback, rating histories, and look for other red flags such as duplicate accounts. Typically if you use a credit card, you should be protected, especially on Amazon. You can still go through wasted time and a big hassle with a scam listing, however.

Most savvy users will easily spot high-end GPUs going for too cheap, but a more novice shopper may be unaware. Remember to cross-reference prices with other known retailers as well, and see if they're offering similar deals. If Best Buy has the same sale, it's likely legitimate. It also helps to be a part of PC building communities, and reading publications such as HotHardware. This will help you develop a strong "Spidey-sense" when it comes to what is legitimate and what's just fraudulent, criminal activity.
