Predire 50x full set brand new never used

so I looked this up on the internet depending on which site you go to it retails for anywhere from 2400 to 4000$ It was given to me as a gift from my ex boyfriend. It's brand new never used it has all 6 bottles. Collagen, Vitamin A, Hyaluronic, Vitamin C, Argen oil and 24k gold and the infuser as well. I'm letting it go for a great deal cause I don't want any reminders around the house so I just want it gone there are a few other items as well which I will list.
