Reviews summary

The app is highly praised for its effectiveness in blocking discount codes during sales and for its great support. Users appreciate how easy it is to set up and how it addresses a major flaw in Shopify. However, there are some issues reported with the app not allowing discounts on certain products, particularly when multiple items are in the cart. Despite this, the customer service team is responsive and quick to resolve any issues, making it a recommended app for preventing discount code misuse during sales periods.

This app tries (and largely succeeds) in fixing a major flaw in Shopify which Shopify themselves have been ignoring for years. Must have app, also great support.

This app will remove the discount code from the cart for products that have 'compare at price' pricing. However, when I have multiple items in the carts (items that SHOULD be able to be discounted), it does not allow any product to be discounted.

Thank you for your feedback. Unfortunately due to Shopify API limitations we don't have control over, this is not possible. Once there will be a technical solution, we will make sure to implement this feature. At the moment, this is the best solution you can have.
