Hi, are the 2checkout plugin for woocommerce a one time payment items? or may be their use is restricted to only one website and that is all ?
All Items license for each single application. A single application means one unique end product (which can be copied and made available to end users of that product). So, You can use that license(purchase code) for your production final application/website. Each license will work for a single website. All Items are one time payment but for support you can extend support when support period will expire(after six month of the purchase).
