Coupons with eVouchers

[inspiration100]

Does anyone know if B1G1 Coupon and eVouchers be used for the same transaction? I,E. Can you use a B1G1 and pay for the remaining fare using an eVoucher?

I don't know why not. The e-voucher is the equivalent of cash, as long as it is used to pay for Amtrak travel.
