Plugins for WordPress with lifetime license
is a great way to save money if you own the site and want to invest the money once to keep working and not think about the fact that you have to pay periodically for plugin updates, because there can be more than 10 such plugins on the site. The benefit is obvious, that paying once is much better than paying for 10 plugins every month or year. It's also a great choice for developers who want to supply their customers with the latest versions of plugins and not have to spend money to buy a plugin for a customer every time. Unlimited license
plugins are a good deal for agencies and developers who create a lot of projects and it's important for them not to have restrictions on creating sites, as well as getting support from plugin creators.
