Why have you asked all these questions before yet it shows only 4 post? Meaning why the fuck do you change your name to ask questions in here? Is it because they are so fucking terrible? J/k First like the title says..that all depends on what the vendor offers...Express is over nite 95% of the time. So it seems that is your best choice. And unless a vendor offers Fed ex.. Usps Express is the fastest available. And before some super nerd brings up a courier or something like that..that would not count. As no vendor uses them. Except for Lim if you buy HIS armor vehicle YES YES YES YES to all your other questions. Unless you are in Antarctica or Africa (my bet based on your questions) you could choose the slowest service and still get it by Friday as long as the vendor mails it out on Tuesday. Ask these questions to your vendor. That is what he is there for and I am sure he would love to hear from a customer. Especially a new one. I know your nervous and new and we have all been there. So just take some breaths and relax. Read your vendors.... vendor page. A lot of those questions should be answered there. Also ....as to Bit instant giving them an address that is in SR is fine. Though some of the Security Guru's might have a heart attack me saying that to you. But the truth is it is fine. Your transaction is all going to be based on how good a vendor you chose. Since most are awesome..Your all good. Smile and realize you are less then 5 days from doing drugs you bought off the internet with BTC....Pretty fucking cool
