Answering the question is completely optional - not answering won't stop the sale from being completed - so it shouldn't be viewed as spam, or an annoyance to buyers. So, what customer service questions would you want to ask?
Here's the original post from Business Topics (some other threads have appeared too), and the basic instructions are:
- Log in to your PayPal account
- Under "my account" click "profile"
- Under "selling preferences" click "custom payment pages," then click "options" and go to "merchant service options"
- Check "add a customer service survey" and fill in the blanks
- Make sure you click "SAVE" before you exit.
