### Price comparison

The module allows you to search for a specific product in the Sovrn database and obtain all offers for that product. You simply need to provide a product URL from any supported retailer.

### Price filter

Sovrn API provides a simple search function that returns all products with keywords in the product title. To find the desired product, it is recommended to add a filter by price.

### Merchnat domains

Unfortunately, the Sovrn API does not return direct product URLs or merchant domains. As a result, some merchant domains may not be detected correctly. To resolve this, add the following code to your `functions.php` file with merchant-to-domain pairs like this:

```php
function my_viglink_merchant2domain($m2d)
{
    $m2d['Verizon'] = 'verizon.com';
    $m2d['Lowe\'s'] = 'lowes.com';
    $m2d['Dell'] = 'dell.com';

    return $m2d;
}

add_filter('cegg_viglink_merchant2domain', 'my_viglink_merchant2domain');
```
