I am having a destination wedding in Riviera Maya, Mexico and a reception in KC when we return home. We have around 30 guests coming to the wedding and I would like to do some kind of gift for those that come (I have different favors for my reception). I have already gotten personalized koozies but I would like to do something else to go with them. However, I need to find something REALLY CHEAP because my budget is dwindling quickly! Any Ideas?
