Reps Question

I’ve lurked for a while and have bought from a trusted rep here and I’m super happy. Trusted Reps buys peace of mind. With that said, I have noticed a few reps on instagram that are unknown. Out of curiosity I messaged one for the price of a small love gold ring. Asked if it’s 18k solid and saw some screen shots of reviews. She said the price was $280. Has anyone tried buying from an unknown rep with a price this good and been happy?
