Not much of a shortage. I just checked and they are all available for pickup right now at my local small city store. Compared to other products they are still extremely available.
Given what a mess shipping has been for the last two years, they appear to be taking the "underpromise, overdeliver" route on shipping quotes.
In some cases you're finding far flung regions relative to the source having better availability, because they were allocated a percentage of the original supply but are also too far away for scalpers to be interested, so they just haven't gone through it as fast. Australia hasn't had too many troubles with some items that are pretty hard to get elsewhere for example. Getting a 3080 in NYC is probably a real challenge, but I can walk to my local parts store and pick one up no dramas.
