Our credit card purchases are currently in maintenance until further notice, and unfortunately we don't have an ETA on when the credit card purchases will be back online at this time.
We apologise for the inconvenience this causes, but if you lodge a support ticket here we can send you an email once credit card purchases are available again.
It is worth noting that buying NoLimitCoin (NLC2) directly from us using your credit card has a 10% higher price than you can get from the exchanges like Bittrex or Cryptopia, this is to cover the expensive credit card merchant fees we pay and to also encourage people to purchase from exchanges.
We recommend to buy NLC2 from Bittrex, to do this you must buy Bitcoin first from an exchange like Coinbase.com and then transfer it to an exchange like Bittrex to purchase NLC2. If you are from the USA, Bittrex does now allow residents of non restricted states to deposit USD Fiat currency directly.
