I am starting to understand other's perspectives on this. I just hope people understand my own. What I will share is that I NEVER cleared any shelf in ANY store. I always left bars for others, and plenty at that. However I will also share that I went to more than 1 store. I could have easily saved myself some time and cleared out a single store rather than save some for others.
In my personal experience, what I ended up doing was buy for example 32 bars, and the rest groceries , etc. This ended up lessening how many points I actually used to redeem. Of course, early in the day I didn't know you coudl redeem for points and still get bonus. At that point the promotion was hardly that great with all the mark up at SDM.
So to all those who hate what I did, I really feel bad as I think you have been mistaken by my 'hoarding'. This was no different to me than a 20x the points event where I stocked up on toilet paper to get more points for more toilet paper. The only difference is that the items was chocolate, which I don't really eat. But points are points.
