EDIT: New promotion is for $10 off, making it $49.75
I have NO idea if it's a real Ring contender, but for $54, I rolled the dice.
This is the Zmodo Ding with 2 door/window sensors and a wifi extender in a holiday package for $53.77 after 10% promotion. I simply clicked "redeem" in the promotion details and it took 10% off. This was the only item I purchased, there wasn't any other requirement.
