Unless his profit margin is less than 2.5%, then he'd actually be losing money

Sounds too good to be entirely true. I wonder what his margins are and if that 20k in sales is directly from Adwords or total sales for the site. If it is just from Adwords I would try to spend more like 5k per month and see where that gets me.
