eBay's comics marketplace inexplicably grew to the size it held during the Christmas 2016 season. Atomic Avenue has hit some big strides in regaining its inventory. Its about midway from the bottom-out point to its all-time high. Comic Collector Live consistently averages a little over 1% growth each month of their userbase. Amazon's collectibles marketplace took a big hit this month as its number of listings dropped by a little more than half. HipComic has shown increases of more than 35% in the past year for its listings. Bonanza's number of listings has shown strong gains in the past year - up nearly 40%.
