What about a Consignment Sale?

I am officially about to go to my very first consignment sale,,My friend called and told me that some rockin' deals on double strollers,and anything I can do to save $300 is good with me! I have to admit,I'm not uber excited to go...I imagine a place like goodwill,only worse,,people's junk thrown everywhere in some dark room, and the smell of mothballs in the air..hopefully it will exceed my expectations! Wish me luck in my money saving endeavor!
