What Our Customers Say
Real reviews from Shopify merchants using our apps.
I wanted to separate the variants of my products and looked for apps. I ended up with this one, but my theme wasn’t compatible with the app. However, the support team was immediately there for me and set everything up right away. I can highly recommend this app!
ABSOLUTELY FANTASTIC! Shopify is limited for filters that you can apply to viewing orders which made it difficult for order fulfillment. They suggested using this app which does not disappoint! Even if there were missing features you have the ability to chat with their developer who is very personable and delivers! We got our wish list, thank you Tan at DEL!!!!
Excellent support, was able to solve the integration of the app with my theme. Now the variants problem has been solved for me
Excellent app!! I searched a long time to find an app that can easily delete old orders in bulk. When I had a question, I sent a message in the chat feature and the developer responded very helpfully in minutes! Highly recommend.
I was looking for a way to display a product cost range on Collection and came across this amazing app in the Shopify App Store. As a newcomer to Shopify, I initially struggled with the setup, but Tan from customer support was incredibly helpful in guiding me through the process and ensuring the app met my needs. I highly recommend this app—it works perfectly, and the support team is reliable and responsive if you ever need assistance!
