|Setting up buyer requirements
You can specify buyer requirements to manage the types of buyers who can bid on your items. Doing so reduces your exposure to buyers who might make sales difficult for you, but it also reduces the number of potential bidders and buyers for your items. You can specify buyer requirements for all your listings, or you can specify the requirements only for particular listings.
To add buyer requirements to all of your listings:
In My eBay, place your pointer over the Account tab, and then select Site preferences.
In the Buyer requirements section, click the Show link, and then click the Edit link.
On the Buyer Requirements page, select your buyer requirements. For example, you might not want to do business with buyers who:
Don't have a PayPal account
Have unpaid items recorded on their account
Have a primary shipping address in countries you don't want to ship to
Have reportedly violated eBay policies
Have a negative Feedback score
Are currently winning or have bought a large number of your items in the last 10 days
If you want to apply these settings to all current and future listings, select the Apply above settings to current and future listings check box.
If you want to prevent blocked buyers from sending you questions about your listings, make sure the Do not allow blocked buyers to contact me check box is selected.
Click the Submit button to save your requirements.
To add buyer requirements for a specific listing, you can specify your requirements in the listing form.
