Extra Gable Boxes

Hey, everyone! So, I need 4 gable boxes for my OOT guests. I've tried the websites and they all sell in quantities of 100!! So, I was wondering if anyone knew of any websites that sell individual boxes. I already checked AC Moore, Michael's, and, for good measure, Office Max. I've had no luck!

I also was wondering if any brides had any extra that I could buy from them?!! I would be so grateful!!

Thanx in advance!
