First – differently than any other similar plugin, this plugin is based on MIT license, which is a holly-grail for premium theme authors on i.e. ThemeForest or similar marketplaces. 
Differently to standard GPLv2 license you are not required to open-source your theme and you CAN include this plugin into your premium websites bundle packs. 
I do say here bundle packs, because you should never have an deals section to be a part of your theme, because that would be a bad idea – you need to leave your customers a flexibility for the future scale: 
What if your customers will decide later go with some kind of fancy e-commerce marketplace system like in Amazon.com – if your customer will grow that big, he won’t need to have deals plugin anymore on their website, he will want to replace it with that fancy e-commerce marketplace system. 
So my advise is to include this plugin in your bundle pack’s <code>/Optional Plugins/</code> folder, so that you can tell about in the installation instructions, but make it fully independent from your theme.
Second – this plugin is fully MVC + Templates based. This means that it’s code is not related at all to it’s UI, and that allows you easily to override it’s UI templates and Assets (CSS, JS, Images) by your theme very easily (and there is detailed step-by-step instructions given how to do that). 
This means that you making a theme to be what the theme has to be – a UI part of your website, nothing more.
Third – it is much more secure than any other plugin’s on the market. It is based on top-end S.O.L.I.D. coding principle with input data validation with data-patterns, output escaping.
Fourth – this plugin is scalable – it’s source code is fully object-oriented, clean & logical, based on MVC architectural pattern with templates engine, compliant with strict PSR-2 coding standard and PSR-4 autoloaders, and easy to understand how to add new features on your own.
Fifth – this plugin works well with big databases & high-traffic websites – it is created on optimal BCNF database structure and was tested on live website with 1M customers database and 500,000 active daily views.
Sixth – it does support official WordPress multisite as network-enabled plugin, as well as it does have support WPML string translation. 
At this point, if you need more than one language, I’d strongly advise to go with official WordPress multisite setup, because it is free, it is official (so you will never need to worry about the future support), and, most important – WordPress multisite is much more suitable for websites that needs to scale. You don’t want to have that additional translation bottle-neck code layer to be processed via database.
Seventh – it has nice user experience – it’s has a default design, it does allow you to have more than 3 deals via different slider’s slides, as well as fading in and out description on mouse hover – so it is not static like what you usually get with Gutenberg.
But the most important is that this plugin is and always be ads-free. I personally really hate these freemium, ads-full or tracking plugins which makes majority of the plugins on w.org plugins directory (and, actually, many of premium marketplaces). So this is the key features we always maintain: 
1. Never track your data (nor even by putting some kind of GDPR-compliance agreement checkbox, like <code>Error Log Monitor</code> plugin), 
2. Never make it pseudo-ads-full (even such a big plugins like <code>WooCommerce</code> or <code>Contact Form 7</code> has nearly 80% of their home screen or 20% of their main buttons about <code>how to install \ buy other plugins</code> 
– this is a really ugly behavior of pushing-more and going to Facebook-like business, where you get like drug-addicted to company products).
The goal of this plugin is to full-fill the needs of website-starter, that needs a great tool which can last him for many years until it will grow that big so he would grow-out current plugins and would need some kind of different plugins.
And, I believe, that many other developers had the same issue when tried to create their first premium theme or set-up a website for their client. Starting with the issues with license type to the moment when deals section is <code>hardcoded</code> into theme code.
So I wanted to help all these developers to save their time, and I’m releasing this plugin for you to simplify your work. And I’m releasing it under MIT license, which allows you to use this plugin your website bundle without any restrictions for both – free and commercial use.
Plus – I’m giving a promise to you, that this plugin is and will always be 100% free, without any ads, ‘Subscribe’, ‘Follow us’, ‘Check our page’, ‘Get Pro Version’ or similar links.
Finally – the code is poetry – the better is the web, the happier is the world.
