If you give manually via cash or check, or if you setup automatic billpay though your bank, yes; but, if you use the online service provided by PayPal or the credit card service on our site provided by Stripe, no. For payment through American Express with Stripe, the processing fee is a flat 3.5% of the donation. For every other (non-American Express) donation via Paypal or Stripe, the respective company will take 2.2% plus $0.30 of that donation as a processing fee.
For example, for a $100 donation via Paypal, PayPal will take $2.20 plus $0.30 to pay for their processing. MLEFC will receive $97.50 of the original $100.
