Hi Community!
I'm trying to join two data sets with clients A-C in one set and clients A-F in the other using MONTH as common field. I tried the Join tool followed by the Union tool, but this comes back with double entries since the number of unique clients are different in the two data sets. I've attached a mock up and screen shots.
Desired final result:

Sales under $5

Sales over $5

Any ideas welcome! Many thanks!
