I'm not sure how the system decided which offer applied. The only thing that comes to mind is maybe it uses the offers in the order that you add them? Because I think on the 2nd card I added the $19 offer first, and then the $6 one, but I'm not 100% sure. Bottom line is they don't seem to be stackable so be careful which one you add if one is more lucrative than the other.
To help confirm what seems apparent. I added the 10% offer before the 30% offers became available on two of my cards and the 10% was used. So it definitely seems that first added is what is used first. Don't see any way to remove an offer once added either. Guess I'm going back to Staples.
