Is there a limit to the number of devices I can trade in?

There is a limit of 10 (ten) devices per trade-in order. Each device must be tied to a new purchase. 

For example, you can trade 10 Wyze Cam Pan v2 if you are purchasing 10 Wyze Cam Pan v3, but you could not trade 10 Wyze Cam Pan v2 if you are only purchasing 8.
