For example, a $5 fabric protector spray might cost you pennies in materials, but it’s a high-margin add-on that customers appreciate when pitched as a way to extend garment life. Train your staff to mention these options naturally at drop-off—“Hey, we can add a quick seam fix for $3 while it’s here”—and watch the incremental revenue pile up. The key is to keep it relevant and low-pressure; customers hate feeling sold to, but they love convenience.
