My Solution!

Another one where my results don't match.  I'm not sure why Nulls were kept for Merchant1.

As a result, UserID 2 is dropped from my result.

My solution to #25. My results don't have null values in the first merchant (other than the single case where there is only one), as this doesn't make sense for the question.

This was so much harder for me than I expected... I'm not sure if it's a me problem, but is there an easy way to search for a string from one field in another field, but grouped by some other field? My solution does this, but it sure wasn't intuitive to me!
