It's standard post. Cheapest & slowest way to ship especially if the pkg is 13 ounces or more or does NOT qualify as media mail.

Look under the heading "postal product' on the tracking page. If it does NOT state "priority 2 day shipping" , it's NOT. If it was first class, it should state that. Tis standard post......... Hopefully it will get to you by the 22nd.

Good Luck

BTW - standard post is the same as parcel post

Thank you very much.

I ordered a item a few days ago and it shipped on Wednesday 10/15 And since then it has not updated. The expected delivery date is 10/22. I would like to know what shipping class is this Priority or Parcel? Thanks in advance! Tracking number VI787381508US
