There is no fee to sign up for ECHOage and no minimum amount required to use the service. Once your party is over, ECHOage will deduct $2.00 from your total amount per guest contribution to cover payment processing. This fee is paid by you, the host of the party, so that your guests pay $0.00 when they submit their contributions. The fee is ONLY deducted PER contribution, not per RSVP or per guest invited. NOTE: If one family brings 2 children to the party and give one contribution, the fee is only $2.00.
