FWIW,

I called Newmar Corp in Nappanee, Indiana on June 8 to order twelve small window blind clips.

Newmar sent them by USPS regular mail, small padded envelope on June 9.

The envelope arrived August 3. Envelope was fine, wasn't opened and taped again, and the address label was correct.

Almost two months for a small padded envelope is a bit much but at least it arrived.

Mike.
