I am a big fan of promoting software as an affiliate marketer. AliDropship is an awesome piece of software that has helped tons of people create successful dropshipping businesses.
They also have a generous affiliate program that makes it more worth the time and effort of promoting.
I do recommend creating a niche website to promote the plugin. Niche websites are how I earn a consistent income online.
They literally are the best way to make money online while you are sleeping, shopping, or spending time with loved ones.
