At exactly 10:00, I pulled 2 together in Row CC (near the back). 25 minutes later I was pulling upper levels right near the stage (better seats). Five minutes later I pulled 2 seats in Row D (fourth row) which I bought. Doesn't make sense how the better seats were available 30 minutes after tix went on sale.
I find this happening with a lot of shows. If you are patient, better seats will appear.
