You have some many scattered and edited points I don't know where to start.
A tying agreement is not where a manufacturer offers you something for free in exchange for the purchase of a product (like your e book and free action figure example). A tying occurs when the manufacturer conditions the sale of one item on the purchase of a second, differnt item. Here, you cannot buy the mark 9 alone. it MUST be purchased with Pepper. Therefore the sale of the mark 9 is necessarily conditioned on the consumer's purchase of a separate product (pepper).
Second, tying agreements have been found on the smallest of items so your issue with price is invalid. Ex- if I recall Bic got busted for conditioning the sale of razor blades with pens (two unrelated product, called a horizontal tying) Conversely car manufacturers cannot make a consumer use only it's mechanics in repairs (vertical tying) after the consumer has purchased a car.
third, the FTC gets millions of complaints. And btw, you don't call them, you have to submit a written complaint. So no, they can't laugh at you on the phone. And of course not every complaint is successful. But I never commented on the likelihood of success of the same. just that it's an option if interested.
And your posting about effecting bookkeeping, I really don't even understand what you're talking about. The whole post is muddled and you keep editing.
