Query: Not really that funny

I'm an eBay addict, and my sister bought me this book for my birthday. I wanted to write a review for gift-buying relatives of ebayers to see -- just cuz we like ebay doesn't mean we'd like this book. It seems like a funny idea, but the idea is funnier than the actual book. You can browse funny auctions on ebay for free.
