Recommended BINs

[beedb9]

Hey there! First timer here, I have done a lot of research and read AMEX typically has higher limits. But I prefer a second opinion.
1. I am interested in shopping strictly online, so are dumps more successful or CVV2?
2. I've read to call the BIN # to get a balance. Is this Valid?
3. Any recommended sites for SPAM IDs?
Feel free to reply here, or PM me. Much appreciated!
