Client project licensing for different products (landing pages) same domain

Hi, i purchased your template for my client (car brand) , i have to deliver multiple landing pages for different car models and promos.
The domain is all de same, de url are different folders.

Do i have to buy one for each new folder / product? If yes may i recycle for same product(car model) even with different folder(url) name?

thanks.
