Because it is nearly the end of the year and time to buy whatever it is that you think you really need, I went on-line to look for stock boxes. I didn't find any. However, I measured the boxes in the garage and I now have ordered 10 boxes that will hold 180 CDs in long boxes and another 10 boxes that will hold 120 CDs in long boxes. Doing this will allow me to continue to pack the van without tearing my hair out.
The 20 boxes cost me just over $100 and should supposedly be here in a few days.
If I have measured incorrectly, I will be very annoyed with myself...
