Gotchas
The required screenshot is capped at 500kb, which a normal full-width product screenshot exceeds without thinking about it, and it is the only hard limit in the form.
There is no account, so the only way back into your own listing is the private edit link they email to the address you typed. Get that address right or you cannot edit anything later.
Submitting drops you straight onto a paid promotion page rather than a confirmation, which reads as a checkout step until you notice the line saying the submission is already in.
The site answers 403 to anything that is not a real browser, so a maker checking whether it is alive from a script will conclude it is down when it is not.
