The fees break out like this:
We have a Performance Fee of 3% or 5% (depending on the plan selected) and then the Credit Card company has a Nonprofit Credit Card Processing Fee of 2.2% +.30 for Visa, MC and Discover and 3.2% for Amex.
If you went with our Free plan, the Performance Fee we charge is 5%, charged on the total amount raised in your auction.
If you raised $1,000, your total fees would be 5% + 2.2% (7.2% total) = $72. The credit card company also charges .30 per transactions. Think of this fee as $.30 per winning bidder because each invoice we create would be considered a transaction by the credit card company when it's paid.
If you went with one of our Pre-Paid plans, you would pay a little more upfront, and we would lower the performance fee to 3%.
