I did a search but could not devise a search term that failed to send 100s of results - so sorry if this has been asked before.

Now, in the UK, we can see a breakdown of how MR are applied to each transaction I'm confused. Until a month or so ago I was getting double points - 2 to the UK Pound. Now for most tranactions I'm just gettint the normal 1 point to 1 Pound rate but for a few entries I'm getting a 25% bonus or 50% bonus. I've heard nothing from Amex on any of these bonus points.

So does anyone know what's going on?

Thanks for all advice
