December and January are the best times to find deals on new suitcases, since retailers are trying to close out old models to bring in the new ones. In fact, many stores will bundle suitcases together at incredibly low prices. There are many foster agencies that are in need of new suitcases to give to children who do not have luggage. Instead of donating a used suitcase, why not give new ones, especially when you don't need all the pieces from a new set? And if the set you are replacing is lightly used, find out from your local Department of Social Services if it can take it or recommend a charity that can.
