Query: Its about time!

Finally a book that is easy and fun to read that marketers and consumers can learn from. I tried to read Why We buy - lots of great info - but couldn't get through it. Lempert's book is timely, chock full of facts and has already made me a better marketer [and shopper]. I've heard him interviewed before on radio and this is one smart guy who should be listened to.
