Different domain registrar will have different prices for the registries. gTLDs are in general cheaper than ccTLDs. If you want to have many gTDLs and ccTDLs with the same domain name, make sure you add up all the prices.

Some domain service provider have the option to search first .COM then show you the available gTDLs and ccTDLs. If it is available, check the next step if they provide other gTDLs at the much discounted prices. In fact you save lots of money using these tricks.

Do you need private registration also - at what price. That's all for now. PM me if you need more better ideas.

Best wishes,
