Thanks very much for your help. It's very much appreciated.
I finally found it and here is the breakdown.
Using 25,000 reward points for 22% my $100 was worth 870 credits. (odd that tech support doesn't know that number)
And through my entire period for the code my $100 was worth 1170.
I'm not complaining at all since even with 6 transactions (buy & cancel) the site didn't let that backwards transaction happen.
So oh no! Definitely not complaining
