Central Cash and Carry in San Jose is a great place if you're into crafts or throwing parties. It's like a combination restaurant supply, Costco, party supply and bodega. I found 3 x 1000 ft. long rolls of white butcher paper for $60.00. 2 mil plastic bags in a wide variety of sizes, paper plates/cups, bulk condiments. They even had pinatas. Prices all seemed reasonable. If you're planning a big party, it's worth a trip.
