Sometimes you find GREAT things if you purposely misspell keywords into the search bars of etsy or ebay or craigslist or where ever everyday people sell things.
For sellers: misspellings mean that buyers (most likely) won't find you but:
For buyers: you can great deals that no one else knows about!
Trying typing in what you're searching for wrong and see if anything pops up.
Also, sometimes sellers don't know everything they're selling (if it's vintage and/or used) and they may use a more descriptive title than use the actual name of the product (because they don't know it!)
I once found on eBay, a nice lot of about 20 or so vintage 80s charms for about $5 (which included shipping!) If you're even half a fanatic about those cute, cute charms, then you know what a rare find this is. The only reason why no one else outbidded me on this deal is because the seller labeled the listing as "Toy necklace" or something similar to that instead of "vintage 80s charms.
