Today's money making idea of the day is selling clothing to a local second chance stores that buy those items. Go through all the old clothes you have and your kids. Sort them in pile - designer adult and designer kids. Check for local area stores that buy these clothes directly and consignement stores.
Some places that buy good used clothing
Plato's Closet - brand name teen and other designer labels.
Once upon a Child - buys childrens clothing and some toys
Clothes Mentor - designer womens clothing
and also look for local consignement stores - which take a percentage of the sale on your items.
