I deliver newspapers and amazon packages in the morning before starting my main job. It basically covers my car payments with a little extra left over.
The company I work has a contract with them . I scan them with an app on my phone. I get about 10-15 a day and they are all in the same area as my paper route so it only adds a few minutes to my paper route for an extra $15 or so a day. I live in Atlantic Canada so I can't really help you unless you live near me.
I got into part-time modelling gigs, thanks to a friend of mine. It was very experimental at first and of course my first few shoots were free, but since the last couple of gigs I have made some decent amount of money . It also kind of helps out people starting their own projects and ventures , where they don't have to pay hefty fees for photoshoots. Works out good for both parties. On an average, a single gig suffices me with the secondary costs of living for about 2 months.
I built a Discord bot a while ago that I later added a Patreon for, which adds some extra features. I don't make a lot of money with it but it covers the hosting costs and leaves enough for an extra night out every month.
I make my own hot sauce, sell to friends and acquaintances, don't do it consistently, but typically have a few people asking when I'll make some more. Thought about selling at my local farmer's market, but the process is a bit ridiculous.
Re icaprivacy I'd like to see more links like #2. The UK woman who was banned from shops as a real life situation / consequence. The rest are privacy leaks and security issues that my friends and family know of but don't care, until it's real-life as per the UK example.
I used to do transcription on the side but tech has really killed that in the last few years. Still get a few jobs once in a while but really just do it for fun now more than an actual money making thing.
I started baking a few months ago and brought my creations into work. Eventually a guy working there brought me on to work very part time making bread for his family restaurant. Really haven't made much money, it's just for fun now (yes I do like making custom breads, its a challenge) but I plan to keep with it. I think I can approach the idea of starting a ghost-bakery in a year or two.
Business plan is basically come up with unique items for restaurants with their owners and agree that they are exclusive. I make them a special bread and I don't sell it to anyone else. They have it, no one else does. I can't go up against real bakeries and I have no plans to ever even try.
