That's typical of my experience with all of these stock-aggregator sites. Either the best price is some dodgy or outright fake storefront, the item's OOS from the real vendor, or the price is out of date.

Trying to buy things like GPUs or SSDs are a joke. I really wish even one vendor would just implement an actual waiting list, locked to an account with a verified address and purchase history. I'm fine to wait for my purchase, but having to race bots for a lottery ticket purchase is a pain.
