When people up north discard their used clothing it can and often does filter its way to South Texas and into big warehouses where it gets sorted and sold for pennies per pound. Many Winter Texans go on treasure hunts in different Ropa Usada warehouses. It is a different form of "American Pickers" if you are familiar with that show.
I purchased a leather coat (yes, real leather), a golf sweater and two princess dresses for $2. It runs at 45 cents per pound, 35 cents if you are a Winter Texan.
Here are a few pictures of the pile of clothing getting sorted at Leo's Clothing.
