New York Stamp Nys Delivery Times

I've been filling in a lot of single stamp needs in my WW collection with the daily auctions from NYS. Recent deliveries have taken up to a month in a few cases. NYS almost always ships same day and yet this long time to get to me. I stumbled across the issue this week. An order that was shipped Nov 22 had a post mark from the New York Mid Island post office that was hand stamped December 10. It sat in a delayed mail facility for 3 weeks before processing. UGH.

Maybe it was just marked as shipped on Nov 22?
