Hello! I came across a seller with an item I would like to purchase. I estimate the price to be around $10 or less. However, I have a strong suspicion that the seller is someone that I know personally. I would prefer to not deal with them directly, as I value my account's security and anonymity. If there is anyone who would be able to direct me to a middlemen thread, or perhaps a middleman themselves, I would be deeply appreciative. Thank you!
