The video embedded below addresses two issues. It shows how easy Amazon’s #1 best selling lockbox product is to break into (really, really easy).

But more importantly, it shows that the $20 product comes with a $10 Amazon gift card, which you can only use if you leave a five-star review.

And written on the back of the gift card:

Please DO NOT talk or post images about this rebate activity in your review content, otherwise it is invalid.

Assuming this video is accurate, is Amazon aware of this practice? Is this condoned?
