I've worked with Lowe's quite a bit these past few years, most often on our partnership on the very generous Toolbox for Education grant program. Even with all that work, I never really thought of Lowe's as a Christmas brand for school families.
But that's changed this year with two programs that I think are worth a look.
The first is a unique gift card program that works well for teachers. There's certainly plenty at Lowe's that a teacher can use, but the real neat thing here is that you and your kids can customize the cards with a picture (of your child, perhaps?) and a unique message ("thanks for teaching me fractions", "holiday wishes for a great teacher"). Nice concept for something both personal and useful for the teachers on your list. Lowe's customizable cards are here.
The second idea is the chance to buy the cool "build and grow" kits as a gift for your own kids. The kits are classic parent-child projects with all the pieces and step-by-step instructions. And pretty cheap. A nice switch from Call of Duty. Details on the Build and Grow kits are here.
Hope these two ideas help with some of your school or learning holiday challenges.
