Find a
trusted person to buy it for you, and send them the bitcoin.
what if after i send the bitcoin,that trusted person ask his bank to issue a chargeback?
Use an escrow for the assurance of both parties.
Still i can't share my shipping information with someone.I want like virtual private debit card that can work on that site.
Well, considering the fact that you're a newbie, I doubt that somebody would trust you in here. Even if you put your personal details here, no one will trust you. It's either you use an escrow and then have him send your bitcoin to the other party once you've got your item or you send Bitcoins first.
I never said that i am interested in dealing with anyone here otherwise this thread would have been posted in marketplace section (use common sense)
I am just looking for advice on ways if i can use bitcoin debit card to buy this or not. May be some people who know which bitcoin debit card providers are actually good so that can advice me.
