It's no secret that many teachers pay for supplies for their classrooms themselves.

Recognizing this, Target is offering a new 15 percent off discount for teachers on "select classroom supplies, from pens, pencils, crayons and markers to classroom storage and organization and tissues, hand sanitizer and more," according to Target.

The offer runs from July 15 - July 21. Interested teachers should go to target.com/teacherprep to fill out some information, and to receive the coupon code.

The offer is good in person, and online.
