You can allow winning buyers to edit the payment total to account for additional charges or discounts that you weren't able to specify up front (for example, extra shipping charges). If you choose this option, buyers will be able to edit a field when they review their purchase, as shown below:

You can turn this option on or off by going to My eBay:

1. Click on the My eBay button at the top of any eBay page.
2. In the left-hand column of My eBay, click on the "eBay Preferences" link under "My Account".
3. In the Seller Preferences section, click on the "change" link for your payment preferences. Look for the checkbox under "Buyer Edit Option".

Note: A buyer is always allowed to edit the total during payment if:

• You did not specify any shipping costs or did not include the shipping calculator in your listing.
• The buyer has an unusual ship-to location for which you did not specify shipping costs (for example, international locations).

Why allow buyers to edit the payment total?

You might allow buyers to edit the total if your final price has contingencies, such as:

• You have complex shipping options and would like the buyer to select from these options.
• You offer multiple item discounts, which buyers can choose from based on their purchase.

If you choose this feature, make sure to specify payment instructions. These will be displayed prominently to buyers where they can enter the total to pay.

If a buyer pays too little, you can ask him or her to pay the additional amount through any payment method. If the buyer paid through PayPal, you can add the extra amount in a PayPal invoice. A link to send this invoice is available on the Payment Status page.
