As a backer on GadgetAny, once you have made a contribution, you cannot change your shipping address or contribution amount through the platform directly. This policy is in place to ensure the accuracy and integrity of the campaign's logistics and financial planning. 

However, we understand that circumstances can change, and you may need to update your shipping information. In such cases, you will need to contact the campaign creator directly.

The campaign creator has the ability to make necessary adjustments to your shipping details or contribution amount. You can usually find contact information for the campaign creator on the campaign page. Reaching out promptly is important to ensure your rewards are shipped to the correct address and that any changes are reflected in a timely manner. 

GadgetAny aims to facilitate smooth communication between backers and creators, ensuring a seamless experience for both parties.
