Does this mean I am getting another Xfinity Gateway modem/router?

All I wanted was the Wifi Extender, not another starter kit.

I received this email from Xfinity "You’re eligible for a WiFi Extender at no extra cost "

I placed the order, and now I see that I am getting these 2 items

WiFi Extender $0

Getting Started Kit Delivery $0

The kit is what I'm worried about - is that another modem/router? I already have one from Xfinity and do not need another one.

Thank You!
