Frequently Asked Questions
How does the Card Bundle Creator work?
Search the CardVault database of 8,100+ sports cards and add cards to your bundle. Choose a bundle type (Team Lot, Player Bundle, Sport Bundle, Era Bundle, or Custom), set a discount percentage (5-30%), and the tool calculates total value, bundle price, and savings. Then generate a ready-to-paste listing title and description for eBay, Mercari, or other platforms.
What discount should I set for card bundles?
Most collectors expect 10-20% off individual prices when buying a bundle. For common cards, 15-25% is typical. For higher-value lots with premium cards, 5-15% works because the convenience factor is already a selling point. The tool shows you the exact dollar savings at each discount level.
How are card values estimated?
Card values are based on eBay sold listings and auction house data. The tool uses PSA 9 (raw) estimates as the baseline since most bundle cards are ungraded. Values are approximate and intended for pricing guidance — always check recent sold comps for your specific card condition and variation.
Can I save my bundles?
Yes. Bundles are saved to your browser's local storage, so you can come back and edit them later. You can also copy the bundle details to your clipboard for pasting into listings. Each bundle is saved with its name, cards, discount, and creation date.
What makes a good card bundle for selling?
The best-selling bundles have a clear theme: same team, same player, same sport, or same era. Team lots during playoffs sell fast. Player bundles for trending rookies move quickly. Include a mix of values (one premium card plus several base cards) to create a perceived deal. Always photograph the actual cards and list the exact cards in your description.
