i think they cuttin down on it though. like ebay is takin action.
but you might be able to find the shit (gucci fabric) is what you search for. theres people sellin that shit for $20-$30 for a 12" x 12" piece! but theres one person who got that shit for $10. i seen the colors of grey, tan, black, red & blue. the black, red and the blue are tight.
