Take a look at the video attached to this post. It will make you laugh, but we can also learn something from this clip.
Without the music or the camera work, this video wouldn't have been nearly as funny as it is; most likely it wouldn't even be funny at all. Selling shears is kind of like this. You can forget the camera work and music and just show the shears you carry, or you can foster an atmosphere of excitement around them.
Excitement sells! Be passionate about your product! Show what you have with gusto and then get out of the way!
