I just ordered my Wyze Robot Vacuum promotional reward (ie a Wyze Cam Black). There WAS NOT a place to enter the promotional code anywhere during the purchase process. This has happened before and it is a problem with the Wyze app ordering software. I ordered from an iPhone and paid with PayPal.
Welcome to the wyze community @rgilbert518!
Try ordering and using the code on https://wyze.com/shop-wyze.
You should be Elbe to enter it at checkout, but you’ll need to login with your wyze account(same as app).
Thanks. Hopefully I am on the way to getting this resolved.
