Math baby!

Obviously we can’t bring ALL THE TOYS to the Eurofurence dealers den.
So we already have a statistic that tells us what boxes of toys sell best, to make a selection based on how many boxes we can fit into our booth.

What we are currently doing is another statistic: What pairs of toys should swap boxes.
So that we don’t leave any well-selling toy behind just because a box of great products also contains one that is just collecting dust.
