My challenges as a new seller on Amazon

I recently started selling on Amazon and received 18 orders in the last 12 days. However, 7 of these were returned for reasons like “Buyer Return” and “Customer Reject.” The product is a simple DIY kit, and I find the high return rate puzzling, as there don’t seem to be valid reasons for many of the returns.

A major challenge I’ve faced is that most orders come from remote areas with high shipping costs, while local or regional buyers are rare—possibly due to the high cost of targeted advertising.

As a result, my pilot program is currently running at a loss. With the combination of high returns, low margins, and high shipping costs, I’m questioning whether it’s worth continuing to sell this product.

For those starting out, this is something to keep in mind. Have you faced similar challenges, and how did you overcome them?
