Answer:
Avoid any phone numbers like, "1-800," unless they are very reputable and trustworthy. Never call a company that sells pills and products from a different company but is cheaper. It's probably a scam, and it's also probably illegal. Don't trust a company with the same number as another unless they claim to be the same company.
Stay safe!
P.S. The worst mistake one can make is telling a shady website your address. They could rob you, or worse, kidnap you. Only tell websites like Amazon. Not HTML websites with a few drop-down menus.
