Purchase 13,464 miles
$270
Purchase 26,928 miles
$539

The check boxes in front of these $signs were not tickable with a notice saying "! Only MP members may take advantage of this offer".
Then I found "Add MP Number" under my name.

So, I entered my MP number and voila !, see how much they became:
Purchase 13,464 miles
$600
Purchase 26,928 miles
$900

Does this mean if you have higher MP membership level, the charge go up accordingly ?
