One of the few Blogger features that is not free is the ability to publish a blog to a non BlogSpot URL, also known as "custom domain" publishing.
Even though custom domain publishing is not free, it's not a feature from which Blogger / Google directly receives income. The cost for a custom domain registration goes directly to the registrar - and for very real services. The need for payment creates the need for some decision by the blog owner, when purchasing the domain.
Whether purchasing a custom domain from a Blogger "partner", using the "Buy a domain" wizard, or directly from a registrar, you're going to have to provide payment in a medium that's accepted by the registrar.
If you use "Buy a domain", you're limited in choice of payment media. The "Buy a domain" wizard accepts only specific major credit cards, it does not accept
- Debit cards.
- Internet bank services, such as PayPal.
- All bank issued credit cards.
If you cannot provide an accepted form of payment to "Buy a domain", you're going to have to purchase your domain directly from a registrar. If you purchase directly, the choice of registrar is crucial to the success of your domain. Try to choose a registrar which:
- Accepts payment, in a currency that you can provide.
- Provides "4 x A / CNAME" (asymmetrical) or "2 x CNAME" (symmetrical) host configuration.
- Can provide you the support that you require.
Remember that, should you purchase directly from a registrar, you will be responsible for setting up the domain properly - either on your own, or with the assistance of the registrar. In this case, the latter registrar choice criterion becomes very relevant.
