I think Best Buy's system isn't fully ready to accept orders (yet..or anymore...) because one of their APIs is returning a message that the product SKU is inactive (for the full PS5 system). Could be the result of a race condition rather than an actual returned value, but it's pretty suspicious. I'm on the "Continue to Payment Information" screen if anyone else wants to check.
