A little more information:

The Huffington Post has an article stating that the major credit card companies have agreed to not skim money off donations to *some* charities. Each card has a different list of charities they don't skim. This is through the end of February only.

This is the first time Discover has ever agreed to not skim, and it's for Red Cross only.

The credit card companies normally skim $250 million a year off of charities.
