If they start carrying it, ask the owner if you could do a bottle signing at your grand opening in their store. Answer questions about your products and talk about peppers and your passion for making sauces. Brand loyalty for a product comes from seeing the face behind it.
Also, have you ever tried making more of a salty, vinegary type sauce? I'd be curious to try your take on sriracha or Valentina. I love all of your lime/honey sauces that I've tried, but sometimes I want superhot flavor with salt and vinegar.
put your sauce in ketchup packets!!! then squirt some in peoples mouths as you walk by them on the street. you can slip then slip the packet down their shirt back, but they might be offensive.
