To keep prices fair, Misprint compares your price to the current market price when you list.
Your price can be within 15% of market, or within $10, whichever gives you more room. Moderately played, heavily played, damaged and sealed items get a wider 30% range because their prices vary more.
Example: a $100 card can be listed from $85 to $115. On a $20 card, $10 is more room than 15% ($3), so you get $10 either way.
