We work with management to get the best seats available for every show to be sold through MarkKnopfler.com. There is only one inventory for each show for MarkKnopfler.com. People that receive tickets through the Fair Admission process are seated first. Traditional MarkKnopfler.com presales will have all remaining inventory.

Specifically, where MarkKnopfler.com is able to secure 1000 seats for a single show, there may be more than one price point of ticket in that inventory for that show. If there are only 600 of the most expensive tickets then the remaining 400 have to be the next best available and they are generally a little cheaper. 

Fair Admission would randomly assign all 1000 seats in the inventory  to shopping carts and send them out. The people who get the shopping cart have a set amount of time to complete their purchase. A majority of people will not complete their purchase. So, a majority of those 1000 seats will be available in the traditional presales.

People that receive shopping carts do not check out for a number of known reasons that may include: having requested multiple shows and only want to attend one, having seen the ticket price decide it is too expensive, changed their mind, etc.
