Description

- Price alerts. Visitors choose a target price and get an email when it is reached. One-click unsubscribe.
- Block, widget and shortcode. Use the “Price comparison” block, the widget, or
[comparedock template="compare"]. - Bulk import with categories, tags, scheduling (one post every N minutes), CSV upload and a review step.

External services
This plugin connects to third-party services only when you ask it to search for a product or refresh a price.
SerpApi (serpapi.com) – used to read product search results (title, price, image, link) from Amazon, eBay and Walmart. You add your own SerpApi key in the plugin settings. The product name or link that you enter is sent to SerpApi, together with your key. Nothing about your visitors is sent. Terms: https://serpapi.com/legal#terms-of-service – Privacy: https://serpapi.com/legal#privacy-policy
Product images – only when you turn on “Auto-set featured image” (off by default), one product image is downloaded from the store’s image host into your Media Library.
Emails – when a visitor creates a price alert, their email address and target price are stored in your own database and used only to send that alert. Alerts can be deleted from the plugin’s Price Alerts screen, with the unsubscribe link in every email, and through Tools > Export / Erase Personal Data. A suggested privacy policy text is added for you.

FAQ
-
Do I need an API key?
-
Yes. All product data comes from the SerpApi search API, so you need your own SerpApi key (they have a free plan). The plugin does not read or scrape store websites.
-
Which stores and countries work?
-
Amazon (21 countries), eBay (17 sites) and Walmart (US). Target, Temu and more stores are planned.
-
Can I change how it looks?
-
Yes. The Offer list is the default design (and the Mini list for short descriptions). In CompareDock > Designs you can switch to any of the other 10 designs with one click, change the colour, add your own CSS per design, or copy a template file into your theme under
comparedock/. -
Does it slow down my site?
-
Prices are saved and refreshed in the background with WP-Cron. Visitors only load a small CSS file and, when they open price history or alerts, a small script.
-
How do price alerts work?
-
Visitors choose a target price and enter their email. When a refresh finds the price at or below the target, one email is sent.
