Lately a lot of ghost shops, dubious vendors and fake adds show up in google search or youtube videos. The chances are that if this is not an add from a reputable firm like Amazon or Apple it is a scam. This is because Google will not verify (and even not bother if a report is being sent by users) the advertiser.
The scams range from electronic devices, services, gadgets, smartphones and even food. Never ever click a link that Google provides with the Ad tag. Even if this is from a well known company it is better to just go to the next result.
Take care to always pay online with a safe paying method like Paypal (never with direct transfer). If shopping from funny sites (Wish, Aliexpress, Bangood) and need a credit card, use a one time card like the ones provided by Revolut.
Take care!
