The Sig is back on sale today Dec 8th at least. Just ordered one but when I went to check out the shipping was $134!!!! There is no shipping if you pick up in store so that's what I did. Don't know if that is an in-store deal only or not.
Weird. I just ordered the Sig through BP as well and got 2 day free shipping to my residence.
That's coming up for me at checkout as well, though I haven't pulled the trigger. $315 after tax is pretty tempting.
