From my email box:
1. Include Casio Calculators on your Back-to-School Supply List for the 2009-2010 school year.
2. Send a copy of the Supply List along with your name, position, school name, and school mailing address to [ADDRESS REMOVED]
3. Receive a $25 Target gift card directly from Casio.
I understand trying to sell to teachers and trying to encourage the school to order a particular brand. A company asking teachers to promote a particular product to students is crossing the line.
