Yes on both counts. I did a BT from a Walmart SC to my Discover without a hitch--just have a statement handy since the BT might need an address for your creditor for the card you're transferring from (and you'll need the full account number). Anyhow, as long as you're transferring between different banks, I don't see an issue.
Yes!! I've successfully transferred balances from my Overstock and Care Credit cards over to major creditors.
