- Set up separate e-mail account; on-line surveys and mystery shopping sites known to send a lot of unwanted e-mails and spam.
- Expect some jobs earn you points, not cash.
- BEWARE: Researching on-line surveys is still new; not much proof there are good sites out there.
- BEWARE: Mystery shopping jobs that want you to send money in advance are scams!
