Do you mean, how do uploaders pay the FileShoppe fee of $0.01 per 100MB?

We use CarrotPay's 'split-pay' system in order to split the payment into multiple parts, and those parts get sent to the corresponding merchant accounts.

For example, our fee is just US$0.01 per 100MB.

If you upload a 100MB file and you set your own price of $0.10, then the split is $0.09 : $0.01. $0.09 is sent DIRECTLY to the uploader's merchant account and $0.01 is sent to us. We verify the payment, and then deliver the content accordingly.

If you set a price of $0.00, meaning the file is freely available (and can therefore be used for typical file shareing), we share 20% of the revenue with the uploader.

So in the above scenario, an uploader may upload a 1GB file and make it 'free'. If a user downloads it using the premium service, it will cost US$0.10. The uploader will recieve $0.02, and again it is sent directly to the uploader's merchant account.

It is important to note that as CarrotPay supports micropayments up to 1/1000 $1 (meaning 0.1 cent), we are able to split even 1cent payments.

The smallest fee we charge is 1cent.

So here are some examble fees.
0 - 100MB = $0.01 (1cent)
175MB = $0.018 (1.8 cents)
350MB = $0.035 (3.5 cents)
1GB = $0.10 (10 cents)

Notice that we can charge downloaders in fractions of a cent for transactions greater than 1 cent. When splitting payments with the uploader, it is rounded UP to the nearest 1/10 of a cent.
