This is such a tired trope. eBay has improved well beyond when it was just the wild west of third party sellers. I’ve not had a single issue on eBay in the last 3-4 years of purchases. Ive actually had extraordinary customer service through eBay. Recently purchased a used $50 coffee grinder and it arrived with cosmetic damage from shipping. Contacted the seller and they refunded the entire purchase while also letting me keep the item.
