The sharing buttons can be shown on the product page and in “Cart” and “Checkout” pages.
Go to “Share for Discounts -> Sharing Settings” to enable or not the addition and to choose in what spot of the page you want to insert the buttons.
Here, in the Sharing settings section, you can also enable the option Add to cart after sharing which allows applying the coupon automatically once shared the related product.
The sharing URL will be the same as the one of the current page unless you inserted a specific URL in “URL to share”.
Any page of the site can be shared if you have inserted the [ywsfd_shortcode] shortcode in the page.
