I use to use these boxes a few years back, by turning them inside out and regluing them. I noticed this year they are printed inside as well, so I figured it was a bust. I have family outside the state and it is a necessity to mail things, so this year I sent all my grandbabies a Holy Bible NIV, and bought their flat rate boxes.....well they added $2.86 to the price of the box. The first one I mailed, was flat rate, no other cost. Then I went in to mail the other three and bam, bam, bam! $7.81 each was too much, so I bought one bigger box and went to another post office and mailed it for the one flat rate. Now I wonder what the extra was for, any ideas? I'm a windy old bag, sorry. Thanks for the vent.
