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&#x27;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:&#x2F;&#x2F;www.amazon.com&#x2F;gp&#x2F;product&#x2F;xxxx" rel="nofollow">http:&#x2F;&#x2F;www.amazon.com&#x2F;gp&#x2F;product&#x2F;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&#x2F;low price goods on Amazon, especially computing parts that are essentially guaranteed to go down in price within the near future. Overall, it&#x27;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.
