Donut Best Buy
Resource Type: Investigation, Stimulus
Which is the best buy? 16 donuts or 20 donuts?
I like this sign because there is some maths doable in your head. The second 4 donuts are $2, meaning 50c/donut. At that rate, the 16 donuts would be $8.
So the question is really... does the "duck box" make up for the premium price of the second 4 donuts?
