Unusual SDM Optimum points reward
Has anyone ever received a partial Optimum points reward? I had a one-day personalized reward offer of 18,500 points on $75 spend on the usual "almost anything in the store." I bought a $50 SDM gift card and $25 of stuff. I was instantly awarded 9,900 points, or 53% of the offer. My actual spend was 33% ($25) of the offer. Does anyone know why I received this particular amount of points?
