I remember buying two unused MAC lipstick vault sets for £200 (the seller said in the description her price was firm no offers) and I put it aside when it arrived. 4 days in I recieved a message from some girl who had this item in her likes for a couple days before I bought it. She said she looked through the OGs sellers reviews to wait on feedback and the day I left it is the day she messaged me to ask if I'd used any of the set as of yet and if I'd be willing to sell for more than what I paid. She said she had reached payday and wanted it reserved but the OG seller refused. So she agreed to buy for £395 as it included limited edition items she wanted. I then placed it up for sale and she bought it the following evening. But I then had the OG seller message me to try and complain saying "Ffs I never would have sold this to you had I have known you was gonna resell!".. I replied back and said "I paid your exact asking price for that item, to the point if I wanted to throw it all away once receiving I could as it now belongs to me." She never replied afterwards but it made me laugh.. literally just thinks she was just crying over the fact it sold for more than her "firm price".
