Has anyone switched from paper shelf labels to digital ones?

I run a small retail business, and one thing that keeps taking more time than expected is updating shelf prices whenever products change or we run promotions.

For those who have already made the switch, was it actually worth it? Did it save enough time to justify the cost, or did you find that other parts of the process became more complicated?

I'd be interested in hearing real experiences from other small business owners before investing in anything.
