I made it all the way through checkout last night at 6pm eastern time through the steam cellphone app. I backed out of the purchase at the final step because i didn’t want to spend that kind of money on the limited edition, grabbed a 512gb oled instead. I was surprised there were still limited editions in stock and i saw a lot of people complaining about being unable to make it through the purchase process so i decided to test it and see if i could… no issues. I’m wondering if there is a difference between the steam app and the steam website? Either way, hope you have better luck and are able to get one.
