You Drive a Hard Bargain
If you have anything you don’t use, you should probably post it for sale on social media. Exchanging your old goods for cold, hard cash is a lot better than just leaving them in your garage to collect rust. However, you should try and at least post a fair price for second-hand goods.
The OP has no idea how to negotiate. When asked how low they would go on their bike, they replied with 2 miles per hour—any slower and you’ll tip over. That’s not what the buyer asked, but that’s still good to know.
