If i'm only going to be in Chicago for one day what are the best thrift stores to shop?

I sell things on eBay and I have multiple booths at local flea markets. I am going to be in Chicago for one day this weekend and will spend it strictly shopping for items to resale. I am no where near familiar with the area and I am wondering what the best thrift stores are. I mainly look for men's clothing, shoes and accessories, luggage, golf equipment, just mainly guy stuff with some sort of monetary value. Any help would be great! Thanks!
