Working with Function Lab has been a wonderful experience. This app really gives our store the opportunity to customize discount experiences to fit our unique customer needs. With this app, the sky is the limit and I can't wait to see the updates they have planned. Customer service is GREAT! They are kind and patient and, most importantly, CREATIVE in their solutions. If you're tired of hitting walls, Function Lab is for you. I am so glad I've taken the opportunity to grow my company and enhance our customer experience with Function Lab.
