What billing company do you use to take the credit cards? And what happens if some kid uses a stolen credit card?

i know h-sphere can interface with charge.com and verisign payflowpro so i am sure those work really well for the processing. To protect against chargebacks make sure you turn on full avs processing and then the charges only go through with a YY avs result.

We moderate all of our sign ups. So if the info doesn't all match and we can't confirm the validity of the order we don't fill it.

We use authorize.net with our merchant account.
