I found an Amazon listing for the Acer ConceptD 3 Pro CN315-71P-58N0 at https://www.amazon.com/dp/B08CP9FLGC, but, while it seems like a great deal, I'm not sure if it's legitimate. It's $850 cheaper than Acer's own offering for this laptop at https://store.acer.com/en-us/conceptd-3-pro-cn315-71p-58n0, which is surprising considering the laptop on Amazon currently (at the time of posting) costs just $650 USD. However, it contradicts itself, saying it uses integrated graphics while saying "NVIDIA Quadro T1000" in the title, weighs 8.9 pounds while Acer's site specifies about 4 pounds, has many negative reviews (3.5 stars), and comes from a reseller known as "Wholesale Broker (We Record SN)" (I've never heard of it).
I get that Amazon is an authorized reseller, but this is a third party selling on Amazon, not Amazon themselves. Is it legitimate, and does it come with a warranty? Thanks.
