I'm just going to say this about your story...
Well, when you try to literally steal something from someone for way less than it's worth (and you knew that); you run the risk of someone else stealing it for a little more.
Nothing happened to you in your story...so how can it be a bad day...for you?
What if you sold something (unknowingly) for way less than it was worth; and found out later that you were taken advantage of...that might signify a bad day.
Remember...Karma.
