Added rules that update your price based on the condition of competitors offers. Specifically, allow users to set rules for competing conditions such as "New", "Used - Like New", etc.

Example:

• Undercut “New” competitors by $20.00 (e.g., $99.99 → $79.99).

• Undercut “Used - Like New” competitors by $5.00 (e.g., $99.99 → $94.99).
