List pricing is usually expressed in dollars per thousand records, or $/M. For example, a list's base price of $120/M means $120 for each one thousand records, or 12 cents per record. Additional services like selects, keycoding, and addressing options are added to the base price.
Lists usually have a minimum order size that is expressed in record quantity, cost, or both. For instance, a $120/M list may have a minimum order size of 5000 records or $600.
