## I need some good bargaining techniques

I recently bought an ODE text (Fundamentals of Diff Eqtns - Nagle 8ed) a few days ago. The book came and it was the wrong edition (6ed). I contacted the seller and now he is willing to return a portion of my money

He mentioned at the end that "I think refund a portion of your money would be easiest. I don't need the textbook for anything so at least you can get some use out of it. The text cost me 18$to post. How much is it worth to you?" I paid$86 (including mailing fee) for the book, how much should I bargain to get the most out it for my book?

 How did you buy it? A mention of "negative feedback" (or on the flip side, a promise of positive feedback if the situation is resolved satisfactorily) can work sometimes. Of course, this is assuming you bought it from eBay or Amazon or the like.
 No I am willing to keep it, but I just want it cheaper. I kinda accidentally gave him a + feedback. Because I didn't even realize it was the 6ed (the cover looks EXACTLY the same)

I'm confused. You paid for it, but it's not what you wanted. But you want to keep it, you just want it cheaper. How is that the seller's problem?
 Amazon has some sort of promisary (sp?) agreement with their sellers. You could get a full refund + shipping cost if you wanted.
