Research Products: Start by researching products in high demand on Amazon. Look for products that are selling for a high price and are low in supply. You can use Amazon's Best Seller list, Amazon's Product Tracker, and other online tools to help you find profitable products.
Find products at a Discount: Once you've identified a product you want to sell, look for stores that sell the product at a discount. You can use websites like Rakuten, Honey, and RetailMeNot to find coupon codes and other discounts.
Keep Receipts: Keep all receipts and track your expenses carefully to ensure you're not losing money on any deals.
Expand your Product Line: Once you've successfully sold a few products, you can start expanding your product line and testing new products.
Use a Barcode Scanner: Use a barcode scanner app to scan products in stores and quickly check their prices on Amazon. Barcode scanners will help you quickly determine if a product is a good deal and worth purchasing.
Consider the Weight and Size of Products: Consider the weight and size of the products you purchase. Shipping heavy or oversized items can be expensive, so factor these costs into your calculations.
