One data point: I signed up for the service ~ 6 months ago. I do ~ $200 in Amazon purchases a month.<p>I got my first rebate last night: 50 cents back on some RAM that had dropped in price the day after I purchased it. For anyone who is concerned about email permissions, here's the email (automatically sent from my personal account) to Amazon:<p>Subject: I was charged more than current price<p><i>Hey,<p>I am writing you to ask for a price adjustment review on a recently placed purchase. Please reference: <a href="http://www.amazon.com/gp/product/xxxx" rel="nofollow">http://www.amazon.com/gp/product/xxxx</a> and xxx.<p>I ordered a Crucial 16GB Kit (8GBx2) DDR3L-1600 SODIMM Memory for Mac (CT2K8G3S160BM ) for $66.99 on January 10.<p>However this afternoon I noticed that the price is $0.50 less than the amount I was charged, as it decreased to $66.49. As I bought the item recently, and the price has been significantly discounted, would it be possible for you to please start processing a post-order price adjustment refund?<p>Many thanks for your outstanding customer service.<p>Best,
Roy Murdock</i><p>The service also attaches a screenshot of the shipping confirmation to the email automatically, which is pretty cool.<p>I suspect that I would get more value from the service if I purchased a higher volume of commodity/low price goods on Amazon, especially computing parts that are essentially guaranteed to go down in price within the near future. Overall, it's great to have this sort of protection from dropped prices and is definitely worth the email access permissions in my opinion - but at the first sign of a data breach or privacy issue, I will drop the service immediately. I am not affiliated with Paribus in any way.
