Some advertising can be deceptive
Some advertising you see or hear can be deceptive. Most of the advertising you see or hear for supplements or other drugs are always talking about the good things you get from it but always put the bad things or side effects in fineprint or don't even put them on the advertisement. Some products you want to buy need your credit card even if it's a free trial, and once they have your credit card number they can charge whatever they want on it which could go really bad really fast. So always be informed and check the company's rating and see if they are reliable before you buy or give them crucial information like your credit card number.
