No matter how effective various physical goodies are (and they can be sort of tokens of cool, which would make them fairly effective), they are bound to be more effective than something risky, demeaning and inconvenient (basically an equivalent of surprise buttsecks) that is only inflicted on legitimate buyers and that pirates get to bypass completely.
You can't compete with pirates in terms of pricing, you have to do it in terms of added value, be it actual irreplicable goodies or completely subjective stuff like giving your customers sense of superiority.
