The line at 4 is so long that if it makes it through to your order, you won't want them any more (because 3's will be up next).
Fortunately, it doesn't look like it will get anywhere close to your order. You may have better luck with 5's, but IMO you should move fast. A 5 on Monday afternoon may have the same status as a 4 Friday afternoon (or maybe a 3).
By EOD Monday, we may be having this same conversation about 6's.
