Put two cards next to each other and read them in the same order.
- Age. A longer history is the usual reason people buy a seasoned line. Confirm the age is the age of the account, not the age of the company selling it.
- Limit. A higher limit can change utilization math, and it usually costs more. Match it to the balances already on the file.
- Price and slots. A cheap line with no remaining slots is not an offer. The open count on the card is the inventory.
- Reporting window. The nearer window is not always the better buy if the age and limit are thin.
Ignore a seller who leads with a guaranteed point increase. Scoring models are private. The honest listing describes the account.
When you are ready, add the line to the cart. The receipt keeps the description you purchased.
