The payment is broadcasted instantly (1-2 seconds). Fee can be as low as $0.10-0.30 (eg. these donations to the VLC address https://blockchain.info/tx/99ee82b2b8f33ee22c6c51ff4ba198141c4283c702ea212bc9edcad19c33d4d2 https://blockchain.info/tx/99ee82b2b8f33ee22c6c51ff4ba198141... https://blockchain.info/tx/d056b36bdb81f70cf344d4489ba337ad1820e07b0907211ecdff764cb9ed25ba https://blockchain.info/tx/d056b36bdb81f70cf344d4489ba337ad1... https://blockchain.info/tx/445ba8e7559a4f83bcd7fd7adac30cf9fa4e220c25ccc35e9492fff876937fef https://blockchain.info/tx/445ba8e7559a4f83bcd7fd7adac30cf9f...). It's important to understand the difference between a broadcasted transaction (tx received by most Bitcoin nodes, "0-confirmation", 1-2 seconds) versus the transaction being included in at least 1 block ("1 confirmation", ~10 minutes). Some merchants accept 0-confirmation tx, while others require 1 confirmation. But in almost all cases it's fine to accept 0-confirmation transactions: • ordering physical goods online (an order takes more than ~10 minutes to be shipped & delivered anyway) • ordering virtual goods/services (eg. paying for VPN: the vendor can simply cancel the service if the tx is never confirmed) • any low-value real-world transaction (eg. paying for groceries... no one will bother with a double-spend attack to steal groceries) • etc
