// Step 1: Create a virtual Product Called "Envio a Cobranza" with two Variants: Portugal/Spain
// Step 2: Get the Product and variants IDs
// Step 3: replace the following variables with the Product ID (in the product settings URL), Variant Ids (see tip below) and Manual Payment ID (In the payment method URL in the admin panel)

var productId = "2388937"
var portugalId = "1883423"

/* TIP: To get the variant ID of the countries I added this code to the product page and checked the console
<script>
{% for variant in product.variants %}
console.log("{{variant.sku}} - {{variant.id}}")
{%endfor%}
</script>
