Two days after the Houston Astros won the World Series, copies of the Houston Chronicle's Thursday paper hit eBay, going for 20 times the cost of a normal paper.In the wake of the Astros' historic win Wednesday, copies of the Chronicle were often incredibly hard to find around the Bayou City yesterday.The paper printed 6 editions, and more than 525,000 copies of the paper - as Houstonians lined up for hours at the Chronicle's newsroom at 4747 Southwest Freeway to buy copies and commemorative posters.
