SC Back in Stock Notify Me

The app worked good initially, but then I needed to buy tokens to keep sending out alerts. No problem, I paid for the tokens. But now the issue is that you can only get a certain amount of tokens per month. :( This is terrible if you are a business that constantly needs to alert your customers. I will have to look for another app that can accommodate me.

I also had issues with the timing of when the alerts are sent out. It is EXTREMELY DELAYED !

If you are a small business that does not need to update multiple times a month with multiple products ... then you should be fine with this app.
They are good with responding and helping to update your site if you need them too.
