Nope, business days are Monday-Friday. FedEx delivers until about 7:30pm, though, so don't lose hope if you don't get it in the afternoon. Also, the reality is that the product was just updated, and there might be an additional delay. You'll be notified if that's the case, but it's just part of the game.
Wow. That's impressive--I always have good transactions with FedEx, although sometimes their tracking is out of date. Much better than UPS, in my experience, which doesn't seem to try too hard to deliver (never past 6pm and once, he didn't even knock on my door!)
