I'm posting this here instead of the DC forum since this is where the thread is...

I'm a big Diner's Club user, so I have accounts with Webcertificate and C2it.

Webcertificate takes DC and charges me $1 per $50, which is half what it would be using my ClubCash account. I can yank $4,000 from my DC account for $80. Not bad when you need the cash for non-DC spending. C2it doesn't charge anything to transfer money from a linked credit card to a linked bank account. Only thing about this system for "laundering money" is that webcertificate won't do more than $50 per transaction and only $150 in a short period (like 10 minutes). I think the $150 is DC's security checks kicking in because I can go back an hour later and do another $150.
Once I've built up a chunk, I transfer it to C2it and then out to my bank.
It's tedious but I don't think I'll (hopefully) have to move any big bucks again (this was post-9/11/01 cash flow problem).

I think the Webcertificate is a great way to get money from DC for transactions that don't take DC. C2it is a great way to move money to my bank account.

Things I've learned. Keep your transaction below $500. Something at that level seems to trip security alarms at both WebCert and C2it. When I first got the accounts set up, I had to talk twice to Webcert and once to C2it to confirm my activity. They weren't nasty about it, just wanted to make sure that I was the one doing it, etc. Standard credit card security procedures. It's pretty obvious that both systems are set up to limit their exposure to fraud.
