How is profit calculated?

Net profit is your sold price plus any buyer-paid shipping, minus acquisition cost, marketplace fees and seller-paid shipping. Recorded grading costs and returns also affect profit. Estimated fees depend on the marketplace; enter actual fees when known.

Example: a $120 eBay sale − $60 cost − $16.30 estimated fees − $5 seller-paid shipping = $38.70 net profit kept. This example assumes 13.25% + $0.40 on the item price, no buyer-paid shipping, tax or promoted-listing charges.

How do I restore purchases?

Use the same Apple Account used for the original purchase. Tap Restore Purchases on the GrailCheck Pro paywall, or open Settings → Restore Purchases. Restoring checks your existing purchase; it does not buy a new subscription. If no active subscription is found, check your Apple subscription status and contact support.

How do I cancel a subscription?

On your iPhone, open Settings → your name → Subscriptions → GrailCheck, then cancel. Cancel at least 24 hours before renewal. Deleting the app does not cancel the subscription.
