ClickBank Question

As a clickbank merchant, what % of refunds/chargebacks does clickbank allow before putting your account under "review" like paypal does.

I just want to avoid the paypal nightmare I had.

Thank you.

Very good question. I purchased an ebook once and did not feel it was worthy of the money spent. Needless to say, I requested a refund, but I did ask myself "I wonder what limit they have before they ban you as a customer clickbank-wide"
