The ask is different
A donation campaign asks a supporter to give. A product campaign asks a supporter to buy. The second is an easier first conversation for a student, especially a young one.
The economics are different
Donation campaigns keep a larger share per dollar. Product campaigns typically reach more people, because the ask is lighter. [Confirmed program earnings model.]
The learning is different
A product campaign gives students something to explain and something to deliver. Both are useful.
