Do you need to pay to use a Box?

I'm curious, do you have to shell out any money to utilize the services of a Box? I've heard it's a popular platform for file storage and collaboration, but I'm not entirely sure if it's a free-for-all or if there are certain features that require a financial commitment. Could you clarify this for me? Is there a base fee or are there different tiers of service that come with varying price points? And if there are costs involved, what kind of value do you get in return for your investment? I'd appreciate any insights you can provide.
