You can allow your 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 might use this option 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, be sure to specify clear payment instructions. These will be displayed prominently to buyers when they review their purchase. Buyers can then enter the appropriate adjustment and pay you faster because they don’t have to request the total from you. If a buyer pays too little, you can ask him or her to pay the additional amount through any payment method.

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).
