Do you charge transaction fees?

No. Ozcart does not charge you any transaction fees on the sales that you make in your website.  Your bank or payment provider may charge you merchant or transaction fees depending on the payment gateway service that you are using and the plan with them that you are on.  Some shopping cart software providers charge transaction fees on top of the fees you pay to your bank or gateway provider, but at Ozcart you don’t pay any extra per transaction.
