Nebraska isn't the only state that asks 529 plan savers to write for a prize. Last September, California gave $1,529 to two parents for sharing their college savings stories on Facebook.
In February, the state chose 10 winners at random from parents who had written about how they loved their child's school.
Contests and specials aren't the only kinds of promotions run by college savings plans that can help parents. In Missouri, a $500 matching grant program is available during June on a first-come, first-served basis.
The hope of all who run these programs is that more parents will consider saving for their children's college education. In Pennsylvania, more than 50 percent of accounts are opened during the plan's four promotional months.
"Parents know they need to save for college," says Pennsylvania's Rohanna, "But it moves to the top of the to-do list when they have to do it by end of the month to take advantage of promotions."
