On my July statement, I noticed that I received a 5000 pt bonus but I have no idea why. I only use that card for 5 monthly donations and nothing else (unless there is an offer that comes up but even that is rare as almost everything goes to my Aeroplan Amex). Did anyone else receive this mystery bonus? I'm reluctant to call Amex, but curious to know what it's about. There is no explanation on the statement.
