If the price of the Rift S or Quest 64GB is anything above 399.99 it's 3rd party and it's actually sad that Oculus is even selling to Walmart, Amazon, Bestbuy, or anyone else that can purchase multiple orders. They should control the purchase of these units so everyone can get an option to purchase at least one, during this shortage. It's quite obvious that scummy people are taking this as an opportunity to purchase multiple headsets and they are making an easy 100-200 profit and even the Game developers aren't even earning profits like that.
Solution: Restrict the purchase of your product to the Oculus Store and create purchasing limitations.
This will drive more people to this site, increasing the visibility of games. This will also protect your customers from scammers and they can reinvest those additional 100's of dollars on games created by the VR community.
