I'm giving Office Depot GCs this year--considering how much the teachers have to do to keep the classrooms stocked out of their own pockets, it's the least I can do. I try to send things when I can, but with 3 kids in school, it adds up quick!
One homeroom parent has already started a collection for a GC, so that class is covered. Now I'm going to wait to hear from the other two to see if they're going to do anything like that. If they don't, I'll get them myself.
