Selling travel is always good - as well as diet pills, and health related items .. shoot.. just go to linkshare.com you can sell anything under the sun - (well you can TRY to sell anything
)
slap up an information ezine type site - .. find a good 'main' domain .. like buyingcheap.com, for example, and make it
dietpills.buyingcheap.com vacations.buyingcheap.com avon.buyingcheap.com etc etc
