My customers get excited about sweet tooth! They love racking up and points. The set up was easy and it has helped my business grow and now they have included social media likes in the free version. It just keeps getting better!!!

I really love this app. I have been operating for 4 years and usually reward my customers with raffles. Sometimes it's unfair because one time customers win over customers that order multiple times a week. Now that they have added even more features, I am totally in love!

I love the fact that Sweet Tooth is adding more value to their product and therefore adding more value to Shopify users. We can all learn some lessons here...

The H2O team at > and all of our water loving customers > absolutely love Sweet Tooth Loyalty Rewards app. The app is sweeet.

Sweet Tooth is simple. It works out of the box (even though there is no box). And the support staff is on top of their game.

Thanks Sweet Tooth for being top shelf. Five organic sugar stars all the way.
