Can I deduct a charity's credit card fees if I pay them in addition to a donation?

I recently donated $200 to the Salvation Army. I added $8 to cover the cost of the credit card charge.

If you donate money to a charity (by cash, check or credit card) you deduct the amount you donated.  You don’t have to worry about what their expenses are or how they spent it.

So, you can deduct $208.
