Redshift Sports review for Sale Discount Wizard

I am using this app to run store wide and product specific sales where the sale price is reflected on each product page and the normal price is next to it with a strike out. The app is easy to use and the customer support is the best I have experienced with any app developer on shopify - I had a use case that was slightly different than the main app function and within a day of first writing to them they had modified the app to make it work for me - that is not something you find all the time.
