You really want to get a date but your confidence is in the crapper after losing hair, gaining weight or not feeling like your charisma is what it could or should be. Desperate for a confidence boost, you sort through your spam and order a few patches, liquids and pills. You try them all out, only to find the only weight you've lost is in your wallet.
The rest of you is still the same, minus a few hundred you could've used for a toupee. There is no “revolutionary patch” on Internet that will get your fat off by tomorrow; there is no “miracle pill” that will enlarge your breasts or penis and there is no liquid that will grow your hair back. All the pills you will get from your online order (if you'll get any) are just counterfeit or diluted. You want a confidence boost? Diet. Go for a run.
How to avoid: stop believing the fake testimonials in the ads sent to your inbox. The only pills that work are the ones recommended by your doctor and even then, not always. Oh, and “Money back guaranteed”? Ummm…no.
