Just wanted to add to the following thread:

After finding The Spirited Shipper on the web, I did a search here and found Barrel_Proof's recommendation as well, so I purchased some boxes for bunkering. Just a couple of notes:
  • The "regular" boxes do indeed hold the BTAC bottles. There isn't too much room left on top, but they do fit
  • The "regular" boxes do NOT hold the stubby Van Winkle and Weller bottles. You will have to get the Magnum boxes for these to fit.
  • Shipping of these boxes is not cheap!! Shipping for each box is about the same price as the box itself.
  • Nevertheless, the boxes are GREAT! I don't plan on moving anytime soon, but if I do, these should hold up great.
