Hey - selling my bike, D lock, cable lock and helmet for $100 (ONO). All bought new 2 years ago from Walmart - this is the bike (https://www.walmart.com/ip/Huffy-26-inch-Rock-Creek-Men-s-Mountain-Bike-Ages-13-and-Up-Blue/1121295?athbdg=L1200). Very reliable, I use it every day to cycle around campus and surrounding area. Brake pads and cables were replaced in April. It's served me very well and is all in working order with some signs of wear, except the handlebar grips could do with replacing/supergluing on as they don't stay firmly in place (inessential though). Happy to send more pictures or show you on campus.
