Adds price comparison to woocommerce and wordpressThe WordPress Price Comparison plugin lets you add price comparison from any source of prices for a product you can find on the web.
It works in conjunction with WooCommerce and adds new URL boxes to your WooCommerce Product pages in the admin area – simply paste in the URL for each price source you have (e.g. Amazon or eBay) and now when users visit your product page, the price comparison plugin will check prices from those sources live for your users.
This plugin integrates with Skimlinks, so simply enter your Skimlinks ID and you\’ll earn money for any sales made through these price comparison links. Skimlinks can be used to monetize any other exit links you have on your site automatically if you install their Skimlinks WordPress plugin but that\’s not needed for this price comparison plugin to work.
Installation 
Upload the ZIP file and activate the plugin. Visit the settings page to enter your Skimlinks account number. Getting a Skimlinks account number is easy and can be done here.
Configuring Products 
Visit your product pages in Woocommerce and paste in the URL for a page on the web where your users can buy this product (and which contains a price). The price comparison plugin will do the rest and will fetch that price live every time your users visit your product page. This means your users no longer have to go out and check all these places manually making your website far more useful to them.
WordPress Price Comparison Pro 
There is a professional version of this plugin which has premium support and access to more features. You can find out more about WordPress Price Comparison Pro here.

<h4>Display Comparison Sets using Shortcodes</h4>
To display comparison sets in your posts, pages or in other areas where WordPress shortcodes are allowed, use the formats below.
Create a price comparison set using name field:
<pre><code>[dfrcs name="baratza encore"]
</code></pre>
Create a price comparison set using name and brand field:
<pre><code>[dfrcs name="j8006" brand="omega" ]
</code></pre>
Create a price comparison set with a custom title:
<pre><code>[dfrcs name="chaos harness" brand="black diamond" title="{num_products} great deals on Black Diamond Chaos Harnesses"]
</code></pre>
Available Filters
You can further filter the results of a Comparison Set by using the <code>filters</code> attribute. Available filters are:
<pre><code>currency
amazon_locale
image
onsale
direct_url
saleprice_min
saleprice_max
finalprice_min
finalprice_max
merchant_id
source_id
</code></pre>
Here is what each filter controls:
<pre><code>// Return only products which are priced in USD.
currency=USD

// Return Amazon products from US Locale.
amazon_locale=US

// Return only products that have an image.
image=1

// Return only products that are on sale.
onsale=1

// Return only products that have a direct URL.
direct_url=1

// Return only products with a minimum sale price of $10.
saleprice_min=10

// Return only products with a maximum sale price of $100.
saleprice_max=100

// Return only products with a minimum final price of $20.
finalprice_min=20

// Return only products with a maximum final price of $200.
finalprice_max=200

// Return only products from merchants with specific Merchant IDs (merchant_id).
merchant_id=61316,33092,97391

// Return only products from networks with specific Network IDs (source_id).
source_id=126,3
</code></pre>
Merchant IDs <code>merchant_id</code> (MID) and Network IDs <code>source_id</code> (NID) can be referenced on our <a href="https://datafeedr.me/networks" rel="nofollow ugc">Affiliate Networks & Merchants page</a>.
Here are some examples of how to use these filters in your shortcodes:
Create a price comparison set using <code>onsale</code> filter:
<pre><code>[dfrcs name="farpoint 55" brand="osprey" filters="onsale=1"]
</code></pre>

<pre><code>[dfrcs name="aeropress coffee maker" brand="aerobie" filters="currency=USD"]
