Guild Wars 2

I’m curious as to how this feature works. The way it is phrased makes it sound like the units you add are moved up to your position in the queue, rather than each unit having its own place in the queue. For example:

User A posts 100 units
User B posts 100 units
User A adds 50 units (total 150)
User C buys 150 units

Does User C buy all of A’s units or 100 of A’s and 50 of B’s?

You might could test this with alts. Using something that doesn’t sell often.

Edit, err I guess you’d have to use two separate accounts.
