Make sure you are buying items that are highly sellable, meaning that you there is a large market so you won’t have to wait years to find a buyer. And be disciplined enough only to buy items that allow you plenty of markup for resale. Specialization, or at least having most of your products fit your specialization, is highly likely to increase your chances of success.
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.
