UPS charges extra for Saturday delivery. And on Sundays, UPS does not deliver at all. What 2 day delivery means is "2 business days delivery". And like someone has mentioned already, if you order after 1 PM, they ship next day - I think it is reasonable - they do not go to post office after each order being placed. UPS also has cutoff time by the way.
Fractal clearly says on their shop page
Our shipping carrier is UPS. Orders typically ship within 1 business day
I do not want to sound rude (really), but if you have ever ordered something that is how it works.
