Trades
Alfred is mostly famous for trading Mending books, but he also trades other useful stuff. He is not maxed out yet, therefore all of his trades are not unlocked.

His prices will go down if you cure a nearby zombie villager of keep trading with him. His prices will go up if you hit him or break the lectern in the middle of the trading house.
