Creating your return policy
Buyers are more comfortable shopping from sellers who offer clear return policies, even though most buyers will never return an item. We've found that sellers who have clear return policies on their listings typically sell a higher percentage of their items than sellers who don't.
All sellers on eBay are required to specify a return policy, whether they accept returns or not.
Note: Sellers are always required to accept a return if eBay determines that the item was significantly different from what was described in the listing.
How to create a return policy
To create a return policy:
In the Other things you'd like buyers to know section of the listing form, select Returns Accepted or Returns Not Accepted from the Return policy drop-down menu. If you don't see a drop-down menu, click the Change link, and then select Returns Accepted or Returns Not Accepted.
If you're accepting returns:
Select the time limit for returning the item.
Select the type of refund you'll give if the item is returned.
Select who will pay for return shipping.
Enter additional return policy details in the text box provided.
Things to consider
The more clear and buyer-friendly your return policy, the more secure your buyers will feel shopping with you. Consider offering "100% Satisfaction Guaranteed—returns accepted, no questions asked" in your Additional return policy details to drive your sales.
Also be sure to clarify if any of the following applies to your listings:
Restocking fees: Mention if you will charge a restocking fee, and if so, what it would be.
Item condition: Let buyers know the condition of the returned item that would be acceptable to you, for example, "unopened box" or "opened box with all original materials."
