Rudi, I must be misreading your post.
The way I read it, you have spent between 5 million and 10 million francs at the grocery store in the past 12 months. (For other Americans, the exchange rate today is about 1.22 SWf per dollar.)
What am I doing wrong?

For those in the U.S.:
look on pgary's web site under buying stuff - groceries for information about S&H greenpoints. You get 10 greenpoints per dollar at various regional grocery chains (no national chains, alas). These convert to various airline miles. It works out to 0.562 miles per dollar normally, but there are frequent offers of 2x to 5x points/dollar on certain products and/or certain size purchases. The chain in my area, Lowe's Foods, has some kind of multiplier offer essentially all the time. At the moment, they have two that can be stacked: double points on certain products and triple points on any order over $100.
