the extent people will go for not getting it their way
It's not about getting them to honor their price. It's about letting the company and consumers know about their poor business practices. Staples is notorious for Saturday night price mistakes. I usually just get them PMed. If people complain, they still make more effort not to pull that crap all the time.
Here is another nugget. They put out a corporate memo to all the stores this morning not to honor this, no surprise. But they always leave the price up for a few days. I'll give you 2 guesses why they do that.
