Reselling is the act of buying products at a lower cost, and then reselling them publicly for a higher amount. The price difference is collected as profit. To begin reselling products, you will first want to have a vendor for the items you will be selling. This means you want a cheap but quality vendor, I provide these for cheapest pricing to help those looking to begin. Once you have inventory, you will list your selection on second hand apps, such as Offerup, Facebook Marketplace, Mecari, Ebay, Kijiji, etc. Always make sure to use good quality pictures of your products to attract customers. Once sold, collect the difference, and rinse and repeat; remember to re-invest into your inventory to make more frequent sales; this is when having more than one vendor helps.
