There have also been grumblings of a price increase again. My bet is that when the promo ends, a new one will be announced along with a $2-$3 per point increase. I think this is still the best time to buy for now.
Also, you don't actually have to buy tomorrow. Just make sure you leave a message for your guide tomorrow (even after hours is ok). Then they will call you back in a day or two and then you get the contract mailed to you, etc. You have a good 10-14 days to decide and nothing is official till you send the contract back.
So if you really are thinking of buying, call tomorrow to make contact with your guide and then you still really have lots of time to mull it over and see if anything new comes along....
