First, I respect anyone with integrity and respect your position.
Second, I seriously doubt it's less than their cost. Most likely that "misprint" was someone listing it at their price. The pricing markup on things would surprise a lot of people. If they are losing money it's probably not much.
Second, the company chose to honor it...he has every right to ask for it at that price since they sent him an order confirmation. I spoke with an agent when I placed my order on Friday who assured me the price was right and they were getting them back in stock. Things changed this weekend...probably when they realized the huge demand.
Don't blame Quake for wanting a company to honor their agreement. He didn't know it was a pricing error when he sent the order and they are choosing to honor it. From what I've seen on here he is a good guy. Let's not be so quick to jump on him.
