Buying books from alien masterminds

A weird fellow with a halting, stilted manner came in asking about our buying policy. I explained the system in a very confusing interaction filled with non sequitur replies, and he finished up with this gem-

So if you don't want them I'll donate them automatically...that's my algorithm.

After I'd sorted through the buy and paid for the winners, he spoke again.

So, is there any work for me to do?

.....uh, no, we're all set Dr. Lizardo.
