It's been a trend past few years to presell con things, not just toys, even commissions, before the con. And I get you want to maximize your money (certainly with the cost of an artist table now), but I have come into other scenarios where as a walk-in you're too late. Even though you are also at the con day 1 hour one. And especially if you don't live on X or Insta.
I understand what Savage is doing here, this is just a general complaint.
