How do I buy more credits?

Buy a credit pack under Add credits in Billing: 500 credits for $10; 2,500 for $45; or 6,000 for $99. Plus applicable tax.

Pack credits arrive within a minute, are used after your monthly credits and last 12 months. You can buy up to 3 packs a day. A pack you haven't used any of can be refunded within 30 days of buying it, from the Unused packs list in the same section.

Packs are for live plans, and they pause while a payment is overdue.
