Make money online: YES

Selling junk mail as a side hustle can be done remotely from anywhere, as long as you have access to mail and a device to list the items online. There are no hidden in-person requirements reported. Online discussions on Reddit and Twitter show mixed reviews, with some mentioning it as a fun and profitable venture while others find it tedious. The success of this hustle may depend on your location for shipping purposes and access to potential clients who are interested in buying junk mail. It's essential to consider time zones if dealing with international customers. Setup costs range from minimal to low, mainly involving listing fees on platforms like eBay or Etsy. With consistent effort, you could start making a profit within 2 weeks. However, it's important to note that the market for buying junk mail might not be as large or lucrative as other side hustles.
