Alaska Gov. Sarah Palin isn’t the only government official hawking goods online. With the economy continuing to tumble, more state and local governments are using the Web to clear out inventory and bolster deflated budgets. Joseph Hamrick, a 59-year-old construction worker from Goose Creek, S.C., got hooked on one such Web site, GovDeals.com, about five months ago. Since then, he’s gotten good deals on a 1999 Dodge truck in great condition, 36 bicycles and more than 2,000 brand-new T-shirts, among other things — much of which he gives away to charity and co-workers.
