Replied to posted contact number on Craigslist ad. Respondent said ad was placed on behalf of sister and I was should email. Emailed as directed. Was told that transaction would be done via Amazon. Received email from "Amazon" advising me to purchase Amazon gift cards and send pix of cards and codes "for verification" and my item would be shipped at that point. When I didn’t reply, received an email from "sister" saying that Amazon had let her know that they had provided me with the information. Email was asking when they could expect me to purchase the gift cards.
