Discover Deals Confirming Cashback after Review Process

I got an email this morning from Discover thanking me for using Discover Deals.  I started to get used to an email that said that they are reviewing the transaction and I will get another email in 30 days to confirm. 

I had 3 emails and in the third email I saw this:

So Discover has been reviewing the purchases but so far the cashback lines up with what I would expect.  Discover is on the line for a lot of money and I have been expecting them to reject cashback easily.  I have been very careful to always use my Discover card for the transaction.

I am hoping for many more emails like this!
