Many sellers in LBTC have started asking for Govt. issued IDs for big transactions.i disagree with other replies, it depends on the way you want to get the BTC, if you want go without id,etc go to localbitcoins.com.
if you just want best price, then compare prices on different websites, many websites provide a table of that.
Why do it in a one transaction ?!Many sellers in LBTC have started asking for Govt. issued IDs for big transactions.
