The cost of an Xbox will depend on a few different factors, such as the model you choose and the seller you buy it from. To give you an idea of what to expect, the current Xbox line-up includes the Xbox Series X and Xbox Series S. The Xbox Series X is the more powerful of the two models and retails for around $499, while the Xbox Series S is the more affordable option and retails for around $299.
Of course, these are only suggested retail prices and may vary depending on where you purchase your console. You can often find discounts or deals from retailers like Amazon or Best Buy, as well as from Microsoft directly.
If you're on a tight budget or looking to save even more money, you might also consider buying a used Xbox from a reputable seller. This can be a great way to get a console at a lower price point, but it's important to make sure you're buying from a seller you can trust.
Overall, the cost of an Xbox will depend on the specific model you choose, where you purchase it from, and any deals or discounts that may be available. It's always a good idea to do your research and shop around to make sure you're getting the best possible price.
