The gold piece/silver piece system from past years is gone; TTE does not support it. Instead, you will be allowed one or more "featured" events, depending on your badge type and as many other events as you care to try. This is one reason why you will not be able to pre-fill your carts this year. At the moment, we are reviewing our featured events and moving as many as we can off the list so as to make the most events available to the most people. Note that the Artemis event collects a fee (I think $2) at game time. I also see that this is not mentioned on the site. I shall fix that as soon as I can.
