Can Someone Explain This Tracking To Me?

I've never seen anything like it before. It said on the listing that the seller was in the U.S., one state over from me in fact, and it is a 3 oz strap for a CPAP machine, free shipping. Smart package between USPS and UPS?

Thank you.

Looks like I'll get it tomorrow. Thank you everyone!

Well, I received the item, late of course, and left neutral feedback saying something like, "item as described, good price, but arrived late. This item ships from China, not New Jersey, so buyers be aware that the shipping time is not accurate." The feedback is now gone. Oh well.
