Setting the Price
The THEN section defines what happens when a listing matches a rule's conditions. The core of every THEN section is the Set Price block — it determines the base price before any adjustments.
Set Price Modes
The Set Price block supports three modes. You switch between them using the toggle buttons at the top of the block.

Single Variable
The default mode. Pick one price source from the dropdown, and the listing's price is set to that value.

When to use: Most rules. If you know which market source you want to track, this is the simplest option.
Example: Set your price to match TCGPlayer's lowest listing for Near Mint cards.
First Defined (Fallback Chain)
Market data isn't always available. TCGPlayer might not have a listing for an obscure promo. Card Kingdom might not carry a particular set.
First Defined lets you list multiple price sources in order of preference. The system uses the first one that has data, skipping any that are unavailable.

To use it:
- Click First Defined in the mode toggle.
- The first dropdown shows your primary source (e.g., TCGPlayer Low NM).
- Click Add fallback to add a second source (e.g., Card Kingdom Retail NM).
- Add more as needed. The last entry can be a fixed price as a final safety net.
The numbered list (1, 2, 3…) shows the priority. Source 1 is tried first. If it has no data, source 2 is tried, and so on.
When to use: When you sell a diverse inventory that spans multiple marketplaces and you can't guarantee data from any single source.
Example: Try TCGPlayer Low first, then Card Kingdom Retail, then fall back to $0.99.
Fixed Price
Sets every matching listing to a specific dollar amount, regardless of market data.

When to use: Catch-all rules for bulk inventory, clearance pricing, or cards with no reliable market data.
Example: Set all commons to $0.25.
