I have a business account too and have bee sitting at 248/249 (pre-fulfillment) for 6+ 64GB SG for many days now, Was at 304/305 but have since moved.
I don't think it's just the silver 128GB.
Just an FYI .....
I returned my 6Plus yesterday. I didn't classify it as too big ( I've used a Note 3 ) but in practical use through my work day, it just felt awkward and uncomfortable. Frankly, it almost felt too thin and heavy. I had it with the Apple leather case. I did love the large screen and the battery life was unbelievable ( start at 5:00 am and by lunch I was at 90% ). Unfortunately for me, it felt like I was lugging around a brick from meeting to meeting. Too bad as I really wanted to like it.
I'll wait for the Note 4.
