Once you press 'Buy now', funds for the purchase are withdrawn from your account and frozen on the Overgear balance. They stay there until you confirm order completion. To confirm order completion, press 'Confirm delivery'. Until then, any deal details can be discussed in the Overgear chat. After the deal is complete, each Party can give a mark or leave feedback.
In the case the agreed deal conditions are violated, you may address the Overgear arbitration to resolve the conflict and replace funds for the innocent Party.
