TCG Mark calculates shipping at checkout per seller package. Sellers do not directly set a custom shipping charge on each listing.
How shipping is calculated
The shipping logic uses platform rules that consider:
Card count
Package weight
Package value
Seller risk rules for tracked shipping
The system then filters to eligible rates for that package.
Tracked shipping rules
Tracked shipping is required when any shipping-policy rule applies, including:
Package value meets the tracked-shipping threshold
The seller is a newer seller and the lower threshold applies
The seller's loss rate is high enough to require tracking
The seller already has too many untracked shipments in transit
Shipping methods in the current platform
The platform ships around a set of method tiers such as:
Plain White Envelope
Bubble Mailer
Bubble Mailer Heavy
USPS Ground Advantage
USPS Ground Advantage Medium
What sellers will see on orders
On the seller order page, TCG Mark can show the shipping method display name, carrier, whether the method is tracked, base postage, packaging fee, total shipping cost, and estimated delivery window.
