It's lowest price is $80 but doesn't include a developer license (another $360) and only can be used on a "simple webpage" not a web application. The last part is confusing. What exatcly does it mean by "simple webpage"? Does it mean a static web page? If I'm building a ecommerce website, I guess I can't use it?
