On the other hand, it's trivially true that the store which "issues" (caveat explained in the article, they don't actually issue anything themselves) a gift card will accept it as a valid form of payment.
It sounds like the way the parent front is phrased fits that. If they're only willing to pay in gift cards, that's a requirement, so it's likely a scam. If they're also willing to pay in cash, then you can probably just take the cash and be fine?
