Yup, that's what happened. They are $50 each on Amazon US. I think they even included short Ethernet cables, so I didn't even have to root around in the garage to find extras.
FWIW, I got only the 1Gbps speed, rather than 2.5Gbps, because my fiber internet tops out at around 900Mbps and I'm the only one in my family who does anything substantial the local network. For once in my life, I might have enough bandwidth at home.
