Before you shop, be sure to complete our enrollment form in order to designate how you would like your rebate to be applied. If you do not have a student at Cornerstone, you can choose to have 50% of your rebate applied to a Cornerstone family of your choosing, or you can have your rebate simply go towards the PTFA's fundraising efforts for the school. This is a great way for extended family members to support a child's education!
