Should not you tell clearly what is possible and what is not before collecting credit card info?

Hi, i wanted to register and spin up a word press site … i chose digital ocean after comparing it with other providers regarding the quality and the price … but once i started to create a droplet with word press, it told me that i need 30Gb disk at least … which mean i should go with the higher plan (10$). i have seen all the tutorials on the internet with the same word press and ubuntu and with the 5$ plan, and i have made my decision based on that price. i think you should either clearly explain the restrictions or provide us at least with an option to increase the Hard disk capacity without going the full 10$ plan. thanks,
