As the topic is titled, how long is the shipping(I live in NC)? And, whenever I try to track my order from the USPS, it never updates.
Can anyone help about this?

It varies, but I'd say that your order should get to you within a week.

Be proactive! Each order has a tracking number. If the web doesn't update, give the USPS a call and let them have the tracking number. Ultimately, when it leaves BrickForge, it's in the USPS hands - so they'll know better than anyone where the package is.

I work for USPS, my advice would be the same as Armothe's.
The package IS in route but the tracking system does have a few "holes" now and then.
Keep in mind, First Class packages can take up to a week=7 days; Priority is definitely faster, thus the higher cost. I'm over in Oregon and get my priority from BF in 4 days from when it hits the "mail stream".

tracking number? what tracking number? and how come i'm not getting invoices mailed to me like I used to?

From my experience, checking the USPS tracking online is rather useless, as they seem to only update it once you receive the package.
Give it a week or so before getting worried.

Check your spam box and make sure your account e-mail is up-to-date. Our Shipping Faq explains that all orders are now accompanied by a domestic tracking number or international customs number.

checked both of those still nothing, also noticed I haven't earned any bonuses yet, but then again no bonus offers available yet so hmmm.
