The 1.3oz Bag of Coffee

I just ran into the Farmers Brothers rep who was replenishing our floor's supply of coffee (or as my friend Ben calls it, "office brown") and chatted with him for a minute. It turns out that Microsoft has special-ordered those prepackaged bags of coffee with only 1.3oz of coffee in them. Evidently about 1.5oz is normal.

Is this some bizarre cost-cutting measure?
