I've been using Letgo to sell and buy for months. I'm only left to assume that my location has something to do with why most of my experiences have been positive. Of course this brings out the crazies, the junkies, and the creeps. So does Craigslist eBay and other like minded platforms. Use common sense. If someone asks you if it's still available, that doesn't mean this persons about to buy your item. It means they're scrolling through postings and asked about it. That's it. I get 200+ inquiry only messages a week. I also sell items frequently. I've been jerked around too, but for the most part, using my common sense and being polite, I've sold over $800 worth of stuff I didn't want/need anymore. But, that being said, I live in a college town that is notorious for its low crime rate. All in all, don't expect too much from this, use common sense, and read user reviews.
