Typically pre-orders sell out in minutes so if you want to grab one of the first units, it's probably a good idea to wait up.
AT&T, Sprint, and Verizon, and T-Mobile are also taking pre-orders via their websites. Many retailers will also start taking pre-orders tomorrow; however, times may vary.
For contract-free pricing across the various launch countries, please see this chart.
Notably, it appears that Apple may offer Personal Pickup availability with pre-orders this year. Meaning, you'll be able to pre-order an iPhone 6 and choose a local store to pick it up at on launch day.
9to5Mac says, "We’ve independently confirmed this news with several Apple Stores and Apple’s online chat. The option to pickup an iPhone in store will be available during the checkout process and Apple will have a second line for Personal Pickup at each store on Sept. 19, 2014."
If you're excited for the launch, get ready by downloading one of the new iOS 8 and iPhone 6 wallpapers!
