Is there a fee on my earnings?

The prices of the products are stated at gross values and do not include the clearing costs that must be levied when each product is sold. 

For example, let’s examine the following situation:

The cost for a T-shirt is $18.99; the seller determined that the price of the T-shirt would be $27.99, and set the discount to 11%. 

Therefore,

• The final price for the T-shirt, after the discount, is $24.91
• Expected gross profit is $5.92

The clearing fee for $24.91 (PayPal, for example, takes 2.9% + $0.30) is $1.02, which is deducted from the gross selling price on the site.
