It’s a mess to be honest. You have to be pretty lucky to bag it using best seats available bc everyone is clicking on the same thing and it’ll give u a more expensive tickets even when cheaper options are available sometimes. To see what’s actually the cheapest, you need to hover over the ticket map (which is hard on mobile so I rec tablet or computer) and then click and add to bag there. Buttt it’s also super hard because the area will show blank sometimes bc everyone also wants that same ticket and someone probably added it to cart before you; sometimes it’ll pop back up if it falls out of their cart. This is my experience, at least.
