Questions about VCCs and VBAs

[yotano211]

My questions are

1. What are EB and PP VCC AVS and why do they cost so much more then regular VCCs.

2. Can I just buy a regular PP and EB VCC and verify them that way or do I need a AVS VCC or EB and PP.

3. What is the better-instant verify or 2 micro deposits for VBA. I know the instant verify is much quicker.

I have never caught any VCC or VBA so I am very new at this. But I plan to buy tons of them in the future since it appears its much easier to verify accounts going this route.

Thanks for any help
