December 27, 2020 Review Updated.
The customer service came back to me and they helped me to fix an issue that I had, also they are super friendly and helpful.
This app does what it says and it's very easy to use. I also recommend getting the premium to have access to HTML, it's cheap and it's 1-time pay, differently from a lot of the apps here in Shopify, where they ask you to subscribe for a monthly fee.
Nice one. October 02, 2021
The app doesn't work anymore. It's keeping crashing and it's impossible to use.

The app is very good, unfortunately it doesn't work with the chrome browser. Error:
The app could not be loaded This app cannot be loaded due to a problem with the browser cookies. Try to activate cookies in your browser, try another browser or contact the developer for help.


I downloaded the app because I was trying to add affiliate link/banners to my shopify store and couldn't find a way to do it until I found the Youtube video about this app. I downloaded it and I started having trouble with adding the code. Andrew was extremely helpful and I couldn't be more happy with this app. It was exactly what I was looking for.

This plugin works flawlessly. I highly recommend this plugin. Its fantastic that you just pay a once time price no BS subscription and it's cheap. The developers are really nice and quickly respond to any emails. This will be my go-to solution as a designer on any store I work on in Shopify.

You may need to customize some code within the theme if you want full width for example (With some themes), but that is just the limits themes and Shopify put on you. The plugin is amazing.

As a web developer and someone who is creating his first store at, I found this plugin essential and invaluable, especially the custom JavaScript and CSS.

It also took less than a minute to set up!

This is a great app! I've had all kinds of frustration trying to customize my store and although the shopify community is great, I wasn't really getting what I needed. This app makes customizing your store very easy and if you need any help their support is fantastic. Plus I LOVE the one time fee instead of the monthly payment.

Thanks for your positive feedback! We're pleased to hear that you've found our tool so useful. Best of luck with your business!

This does exactly what I need. LOVE that I can specify which pages the code will be added to. I'm going to use this a ton for customizing my store WITHOUT modifying the theme code. That way, when there's an update to the theme, I can install the update without losing all my custom code changes.

Plus, when I encountered a bug, they jumped right on it and had it fixed same day!

Great app, great support. It does everything perfectly when I want to add an additional "Buy now" button on my website. I used Custom CSS and Custom HTML to do that job. Add custom code to the Shopify theme never been easier with this app.
