One of the least appealing aspects of the Amex platinum card is the fact that you get 1 MR point on mosts purchases. As a matter of fact the only 2 exceptions are getting 5X on airfare booked directly with airlines or Amex Travel, and 5X on prepaid hotels via Amex Travel. In contrast, the competition has several categories in which they offer at least 2 points per $1 spent.
However, through Amex Offers, one can find hundreds of deals. Sometimes, the offer is just getting 2x on purchases with a particular retailer, but there are several instances in which the offer might be a lot more appealing, like getting $40 off a $200+ purchase on Nest.com or getting $30 off on hotel when you spend $150. There are instances in which instead of a dollar amount or 2X points, you might get an actual amount of MR points for your purchase. I have also seen 25%/30% off your purchase at a given retailer.
While these offers might not change your life, they keep coming and every now and then, I find a really good offer which has the effect of softening the blow of only getting 1X on most things when using the Amex platinum. While this is not the only Amex card to get offers, I tend to see that the platinum card gets more offers than my other Amex card.
