Women's Wear Daily: USPS Invites Retailers and Carriers to Bid for Same-Day, Next-Day Delivery Access
The U.S. Postal Service (USPS) is opening a bidding process for retailers, brands and logistics companies to gain access to its last-mile delivery network, offering them same-day or next-day delivery.
USPS Invites Retailers and Carriers to Bid for Same-Day, Next-Day Delivery Access
USPS is far from perfect. There are plenty of legit addresses that USPS doesn't recognize. College dorms, new homes or developments, old houses that have been converted to apartments, rural areas, etc. Often when USPS says they don't recognize an address, I put it into Google and come up with a photo of the house or apartment. In that case, I ship.
Why does Etsy allow buyers to put in addresses USPS doesn't recognize
Unfortunately, I have not been able to find a USPS Web site which states this clearly, and so for the moment will refer to this Web page by another source (which has links to USPS Web pages which are no longer active ).
You're close: Attn. In a business letter, though, you're usually better off avoiding abbreviations, and some style guides recommend leaving 'attention' out entirely.
@FrameTowne Did you choose USPS retail rates in one shop and commercial rates in the other shop? That would explain the difference. The $13.98 also sounds like it might be Flat Rate or Regional Rate shipping, rather than Priority by weight. In that case, it could be that your Package Preferences are different in the shops.
