Shopping cart checkout not working on Xbox Series X.

On the site, try placing the item in the shopping cart, then go to checkout and see if the value appears in the correct currency.

Just to add the store app updated again and now there is no wishlist, that is totally gone and there is no cart symbol any longer which means if I add something to the cart and choose to continue shopping there is no way to view the cart or checkout without
having to add a random game to the cart then choose view cart then remove the random game.

Are you referring to the Shopping Cart on the Xbox One Store? That doesn't work for me as it never completes the checkout process (I have reported it via Xbox Insider app).

Have you tried doing direct purchases on the Xbox Store? Those work for me albeit without the convenience of being able to bundle several items into one bill (ie the below $10 purchases on offer).

I had the same issue since this morning. Xbox series X in cart, go to checkout, then error message stating an issue on their end and to “try again in a bit.” I tried all morning into this evening. Decided to call them...On hold with xbox support for 1
hour and 49 minutes before someone picked up only to tell me that the item in my cart is sold out even though i had an order number and expected ship date.

So the xbox series x is in my microsft cart ready to buy but everytime i click checkout it says purchase failed how is it purchase failed if its in my cart?? If they were out of stock it wouldnt be in my cart

Its doing that on all the retail websites. Had mine in the cart seconds after Walmart started placing orders but nothing..full cart but out of stock. The brick mortar Walmart only recieved 18 consoles for launch day?? Its a decent sized city here in the horse
capital of the world. A retarded monkey could of planned this better...but hey at least i can go on ebay and buy one for $67,000.
