US Nonprofit/NGO documentation requirements?

Hi there, we're a US-based non-profit organization. I've already sent similiar message via the "Contact us" form (both today and several days ago). I never received a response to my request from several days ago.

Do you offer nonprofit/NGO discounts, both on standalone products (specific immediate need = WP Folders plus all Addons), but we may be open to buying the full WordPress Bundle?
We have potential use cases for WP Table Manager, WP Ultra Filter, and WP AI Assistant, WP Latest Posts.

If so, what are the discount rates, and what proof/documentation do you need to verify our status?
I'm assuming these are applied using discount codes, so please advise if you provide separate discount codes for different products/bundles, or if it is a single NONPROFIT## discount code regardless of product.

Thanks!
Sean
