I want a new iPhone :(

Hey guys so recently my classmate broke the screen of my iPhone 6S, so I went on the internet to find some place where I could fix it. Instead, I fell over an iPhone 7 Gold for only 300€ (which is incredible). I have for a long time wanted a phone with a Golden back, and iPhone 7 seems like a better phone than the one I currently have. I would greatly appreciate any kind of donation at all, as it will help me a lot. Thank you for taking your time to read this
