Oh bless your heart - sounds like something I did recently with my son's party favor boxes - order 35 thinking they were one but "one" turned out to be a pack of 4! So, yes .... 140 gable gift boxes later .... rofl!
I say decorate them and give them as gifts! Add some cardstock or DSP to the front of them, and add a little notepad to the bottom - maybe like little shopping lists that go on the fridge
Teachers might like them as well - if you have a child(ren) or church, etc, you could print out their name or school/church logo and it would be a nice little thing for the parents or parishners to have to keep handy.
They also stick to the inside of kid's school lockers
Best of luck, hope you let us know what you do with them!
