Percentage calculation with German "financial" paper Handelsblatt

So this is what i saw today, an article about how to save during holidays with the clever selection of credit cards (stupid topic on itself).
But please dont underestimated the savings potential connected with such a choice, as our experts from Handelsblatt explain and calculate:

10.000 and 1/2 percent savings are 1.000 or 2.000 Euros savings in total. Amazing!

Seriously this is an online article and one could say you get what you pay for, however I still think that some kind of quality standard should be maintained. Sometimes it's better to not publish something in my opinion.
Quality has been on the run since a while now, most of their articles online I don't take serious anymore. On top of that they have those image slideshows (every 5th image advertising) which is just ridiculous.
