The social media sponsored ads lure unsuspecting customers into a scam.
They offer a free sample. You are only asked to pay shipping. When you pay shipping on the sample, you will not be aware that they plan to start charging you.
They rely on you not being able to locate the ad in a search, and therefore don't have screenshots of their deception. Once I started requesting a refund, prior to shipment, they stopped replying to me.
Do yourself a favor and resist the lure to order the sample. Buy instead from a reputable company, that doesn't have to resort to deceptive practices to get your money.
