Ordering Online from USPS site, order is still processing?

[Avactionfigures]

I've ordered free supplies for my business. Didn't cost a thing, you just had to create an account and fill out your billing address.
I got an email saying the order has been confirmed. When I go to my Activity History, it says the order is complete. But actualy looking at the info, there is no tracking number? And status for a couple days has just been processing?

USPS doesn't always have a tracking number

Is there a way to find out if anything's been shipped?
