Post Office strikes again

I don't know when they did it, but the large flat rate box got smaller. I used up the boxes I had on hand, and got some more this week at the post office. Went to ship out a part, and found it wouldn't fit. I found one more old box, and compared the size. Old 12x12x8. New 12x12x5 1/2. Can't ship 904 converters in a flat rate box, any more. Wonder if they changed the size of the game board box. If they made that smaller, no more shipping intakes at flat rate.
