I have ordered for flash memory card with Chinavasion. They sent me fake flash memory card which does not work. I have returned back to them and again they resent one that doesn't work either. As i was in quick need, i ordered it from other online store ChinaBuye, i received the memory card on time and started using it with hazzle free without interrupting my business works. Now i am still waiting on with Chinavasion to take their item as i no longer need it and refund my money.
