In a medium-sized bowl, mix together the barbecue sauce, chili sauce, and grape jelly until well combined.

Place the little smokies into your slow cooker and generously pour the sauce mixture over them, ensuring each sausage is evenly coated.

Cover the slow cooker with its lid and set it to the low heat setting for a duration of 3 hours.

At the halfway point of the cooking time, gently stir the sausages to guarantee that they're all immersed in the sauce.

Once done, arrange the sausages on a platter or in a bowl, and remember to drizzle some of the remaining sauce over them to add an extra burst of flavor.

Serve the sausages with toothpicks for convenient snacking.
