We already like Safari Seconds enough to have raved about it here in 2006 and 2008, but the place, a dirt-cheap, refugee-run thrift store that helps African immigrants get on their feet, just keeps on giving. Since moving last summer to a more visible space on Broadway, the shop has hosted clothing giveaways every last Friday of the month, sometimes with a bit of fanfare and African food and music, but always offering secondhand specials at the best price of all: free. Spring cleaning was never so much fun.
