Tokyo Pen Shop review for Notify Me! Back in Stock Alert

This company offered a decent product, but after we were locked in to their system, they raised the prices by hundreds of dollars per month. Unfortunately it is not a simple process to migrate to a new vendor because Shopify imposes an import limit of 1000 records. If you have lots of customers waiting for notifications, you will not be able to migrate. This company was polite, but offered no assistance in dealing with this problem. Notify Me was an expensive, complicated mistake, avoid.
