The Economy postage is untracked airmail. Usually 2 weeks. Once it has been sent, it is out of my hands. Correct value is declared, so you may be taxed, depending on your country.
The Standard postage is 3-7 days tracked, but only available to certain destinations. eBay doesn't allow selecting every country, so it may show Standard as being available to your country, when it's not. If unsure, ask. If purchased, and Standard is unavailable to your country, you'll be required to downgrade to Economy untracked, or upgrade to Express.
The Expedited postage option is 2-6 days tracked, but costs a lot more. You must supply a phone number with the Expedited option. You can supply it in a message with your order.
