In context of the title of the thread, i can say with no doubt, RTX3x series cards have become available in the last 24 hours, where they were not available previously for 2 weeks+ on Bestbuy. The reason i know this is because i personally saw many different versions of the RTX 3XXX series available for purchase throughout today. Both AIB & reference design, from 3060ti to 3090's & i personally bought 2 myself with no bots, or scalper programs, thats a sign inventory is increasing.
i also heard mention of nvidia re-supply RTX 2xxx cards to AIB's, but im not personally aware of an influx of any fresh cards of that make. i can only speak for my personal experience, but i can say i know for a fact others got 3 series cards today as well.
im not saying you are wrong or i am right, im just pointing out my experience. it a good sign for all of us
