Optimal Distribution review for Amai Upsell+ Volume Discounts

We have had great success in using this app. We use it to create discount levels on most of our products. It's straightforward to set up and looks clean and professional on the product pages. When I needed help with troubleshooting and adjustments, Eugenia was possibly the fastest in response time I've seen with any of our applications. Thank you for your help, Eugenia!
