Skype Credit is no longer available. For new purchases, check out the monthly subscriptions or make a free Skype call to anyone anytime.
This a shame, as I liked to keep Skype around as a backup way to make calls and for devices that don't have cellular plans. I was happy to pre-pay and let them take a little of the balance now and then as I had to tickle the account to keep it active. But I'm not going to pay a monthly subscription just to have it immediately ready to make a call.
