Actually have been having purty good 'luck'
Last box I sent was 60# of boolits to WA...med flat rate of $15
Did arrive 2 days late...but box was intact & everything there
I have a USPS account...so I print labels online...
Then drop off at the PO....no wait/no BS
Just printed a $15 label for 1500 pcs 223 brass...wish me luck......
