I like your approach. Coming in under the radar, so to speak, is a good way to build confidence in something. Taking in something that may be off the beaten path (e.g., a new food, information, a different activity) can be so foreign to someone that it can cause them to walk out the door without thinking twice.

But I can see how pre-selling something by showing the benefits one bite at a time can make the difference in a few sales or a lot of sales.
