No. The Flash Gordon level is a little unique, since I am using it to fund just a short run of the hardcovers (instead of upgrading everyone from soft to hard, which would require a new stretch goal. Only those who have pledged $100.00 or more at any level will get the hardcover upgrade automatically.)
The Flash Gordon level stands alone, and comes with a signed hardcover book, a digital edition, postcard, stickers and magnet. If you've already pledged at a "softcover level", e.g., the "Snoopy" level, you may upgrade to a hardcover by adding $30.00 to your pledge. Or, if you pledged at the Flash Gordon level but still wanted a tee, you may pledge an additional $20.00 to have one added on.
The end-of-drive survey will have options for you to request those things that your additional donation may have purchased.
