Question about Britain library donation

[tarugobr]

I want to make some donations to the Britain library for a 550,000 points iten, but i dont really know how to proceed
can i make my donations through board commodity deeds or do i need to go to the library a thousand times with tons of boards to do it?
commodity deeds would make it a lot easier!

They added the ability to use commodity deeds earlier this year. The NPCs will display a green number showing the number of items you the number of items you have, including the deed amount.

Do be warned that sometimes the NPC will act like colored boards are normal ones. Make sure you click the correct color for the boards you have, not normal boards, and only do normal boards on trips where all you are bringing are normal boards.
