Buy exactly the credits you need
Next to the credit packs there is now a "Choose your own amount" box. Type the number of credits you want and buy exactly that many, at the same price per credit as the 1,000-credit pack.
Choose your own amount. On the pricing page, under the credit packs, type how many credits you want and you see the price straight away. You pay for exactly that many credits, once, with nothing that renews.
The best pack price, for any number. Every credit costs the same as in the 1,000-credit pack (about 2.8¢ a credit today), whether you buy 180 or 5,000. The smallest purchase is $5.
Same credits as a pack. They arrive in your balance the moment the payment goes through, show in your credit history like a pack, and are valid for the same time as credits from a pack.
