From their website:
WinRed charges a 3.94% processing fee for every transaction made. Only candidates and organizations you choose to donate to will receive money.
When you make a donation on WinRed, you are donating to a specific candidate or organization, but your donation will first pass through the WinRed PAC for federal committees. For donations to state level committees, WinRed Technical Services is used as a vendor to process donations.

Thank you. I wonder if there is a place to donate directly to Trump/Trump campaign.
do NOT use winred; mail a check; do NOT provide telephone number or email ... address and name OK ...
