My GF works in sales. Nominally she makes $29/hr which is pretty good for someone with only a HS degree, and she is an hourly sales person so she gets time and a half. However, she manages a $1 million dollar portfolio of sales that are already completed and currently in between contract signing and fulfillment, and when the orders are fulfilled she gets .5% of the total contract amount.

Orders take about 6 weeks to be fulfilled barring catastrophe, so when it's all calculated out every 3 months she makes $29 * 62.5 (40 hours plus 15 * 1.5 = 40 + 22.5 paid hours at base rate) * 12 (weeks) + $10,000 bonus every 3 months = roughly $31,750 or $10,567 a month before taxes.

That's almost as much as I make with a BS degree in the tech field. It's crazy, but then again she does work more hours than I do.
