Smart Buy Comparison — Product Comparison Widget (WordPress Plugin)

Smart Buy Comparison is a WordPress plugin that adds an interactive product comparison widget. Visitors pick products and compare specs and price side by side, with a computed Value Score.

What it does

• Drop it into any post or page with one shortcode, for one category or all of them.
• Product picker, side-by-side spec table, price column and Value Score.
• Manage the catalogue under Settings: import a JSON catalogue file, or edit by hand.
• A malformed import is refused and the previous catalogue stays live, so a bad file can never blank the widget.
• Handles messy real-world data, such as prices written as prose and ratings on different scales, without showing wrong numbers.

What you get

One plugin ZIP, version 1.0.3, to install from Plugins → Add New → Upload. Requires WordPress 5.8+ and PHP 7.4+. Instant download.
