Any used travel guide bookshop on Munich in Paris? Anyone has a copy to sell?

I'm looking for used travel guide about Munich and Bavaria in Paris, around 3 years old at the most. I'm reluctant to spend more $ on a new travel guide and the prices are steep. I tried Amazon but i won't receive it in time for my trip. D

I have Lonely Planet, Fodor's and Let's Go, but how would I ever be able to send them?
