Frequently Asked Questions
What is Upsider?
Upsider is an exclusive Stellar feature that automatically scans the comic market to find books with the greatest profit potential from grading. It calculates the difference between raw and graded prices, factors in grading costs, and shows you exactly which comics offer the best return on investment. You can filter by comic age, target grade, price range, and publisher—plus set up email alerts when new opportunities match your criteria.
Can I cancel anytime?
Yes! You can cancel your subscription at any time. You'll continue to have access until the end of your billing period.
What happens to my comics if I downgrade or my subscription lapses?
If your collection exceeds your new plan's limit, only the most recent comics up to your limit will remain fully accessible. Comics beyond the limit will be archived - you'll see a summary of what's archived, but you'll need to upgrade to view or manage them again. No data is ever deleted.
How do I update my payment method?
Click "Manage Subscription" above to access the customer portal where you can update your payment method, view invoices, and more.
Will I be notified before hitting my limit?
Yes! You'll see warnings on your Collection page when you're approaching your limit, and you'll be prompted to upgrade when trying to add comics beyond your plan's capacity.
