INSIGNIA 50" Class F50 Series LED 4K UHD Smart Fire TV

This item was delivered to me last week by Amazon. It was a gift from an Amazon gift list that was set up for me by a Good Samaritan. After 25 years of homelessness I had finally moved into my own place. I opened the box to try and find the packing slip so I could return it, but there was no packing slip. I needed to refund in order to purchase items I am desperate for (broom, laundry detergent, cat food and litter, bathroom and kitchen supplies, etc) I have been unsuccessful in trying to return it to Amazon for complete refund without the order number. My only option was to try and contact the anonymous gift giver. I refuse to do that for obvious reasons. I am selling it for half the actual sale price the person had paid for it. I am asking $120 but will be accepting best offer should it not sell by this afternoon.
