How to implement price break pricelist

Hello

How can I make a price list for single item:
1: 3USD/pcs
50: 2.5USD/pcs
250: 2USD/pcs

Thank You

Have a look at Pricing Rules

Hello

Thank You! What would be the correct way to use pricelist/price rules. If I have only such type prices then only rules?

Thank You
