Been a while since I've found a box even that good. I've only found 4 x 40% out of my last 965 half rolls searched (over 19 boxes). Maybe its time for me to take up digging too.
Sounds like a great box to me! I have 16 boxes coming Monday (if all my order banks come through!!) I would be grateful to find 3 40%ers with the way my box numbers have been lately. Good luck with the rest of your box!!!
