According to The New York Times leaked internal documents outline plans for IRL Facebook stores through which it would sell its VR headsets, AR glasses, Portal devices and more:
|"Meta has discussed opening retail stores that will eventually span the world, said people with knowledge of the project and company documents viewed by The New York Times. The stores would be used to introduce people to devices made by the company's Reality Labs division, such as virtual reality headsets and, eventually, augmented reality glasses."
Right now, you can buy Facebook's products in retail stores, but they're lining the shelves alongside many other competing devices and options, and don't generally get specific focus. If Facebook wanted to invest more into direct marketing, and showcasing its next-level plans, it would be best-placed to do so via its own, dedicated promotion and product displays, which it could directly control within its own stores, built specifically around its offerings.
