Being able to buy and sell secondhand items online is a huge perk of the Internet. People can sell things they aren't using anymore to make some money back on them; this also helps reduce waste. People can also find the things they need at a cheaper price, scoring them a good deal.

There are many places online where people can buy and sell things, eBay is one of the originals along with Craigslist, and now Facebook Marketplace is a widely used site as well. The only thing about sites like these is that literally anyone can post things for sale on them, meaning there are some truly odd products that pop up from time to time. Some of them might be a joke, but it's hard to say for sure. Users on Reddit have shared many of these strange finds with the world, so everyone can see what's for sale out there. Here are just 24 of the strangest finds that left people questioning the sanity of others.
