Why it matters
Most domain sales happen in .com. Buyers trust it, type it by default and expect it. For that reason a .com name usually sells for much more than the same name elsewhere. Wholesale registry fees are capped by contract, which keeps renewals low and predictable. A common mistake is treating a brand in another extension as equal. Many companies start on a cheaper extension and later buy the .com to protect the brand.
