Banner advertising, when set up using a system like I presently use, can be very hands off – in fact for me it’s entirely passive – assuming there is an audience that the sponsors benefit from advertising to. It’s difficult to make loads and loads of money just from banners unless you have significant traffic, but it is easy enough to make some money from it and once you do, it generally proves very reliable unless you stop updating your website.
Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy. Food delivery services send a box of food every week with new, sometimes unique vegetables, meat, fruit, and so on. If you don’t have time to shop and want simple meal-prep that leads to a good meal, a food subscription service may be perfect for you.
