Coffee or donuts?

First time I saw this ad I wondered just how many donuts 2lb actually is.

Surely it would be easier to say 6 or 12?

Then I took a closer look and realised it's actually 2lbs of coffee that they're giving away, not donuts.

Why?

Free petrol? Absolutely.

Discount on insurance? Why not?

Even 2 cups of coffee would be good.

But 2lbs of coffee?

Where on earth did that idea come from?

Thanx to MLB
