There are several ways to source products for your ecommerce website. Here are some methods you can consider:

1. Dropshipping: This is a popular method where you partner with a supplier or manufacturer who handles the inventory and shipping for you. You list their products on your website, and when a customer places an order, the supplier ships the product directly to the customer. Examples of dropshipping platforms include Oberlo, Spocket, and AliExpress.

2. Wholesale Suppliers: You can work directly with wholesale suppliers who offer products at discounted prices when bought in bulk. This allows you to have more control over the inventory and shipping process. Some well-known wholesale directories include Alibaba, SaleHoo, and Worldwide Brands.

3. Manufacturer Relationships: If you have a unique product idea or want to create your own brand, you can establish relationships with manufacturers. This involves sourcing products directly from factories or manufacturers, often requiring larger upfront investments. Websites like Thomasnet, Makers Row, and Alibaba can help you connect with manufacturers.

4. Print-on-Demand: If you want to sell custom-designed products like t-shirts, mugs, or phone cases, you can use print-on-demand services. These platforms allow you to create and sell products with your designs, and they handle the printing, packaging, and shipping. Examples include Printful, Printify, and CustomCat.

5. Retail Arbitrage: This method involves finding discounted products from retail stores or online marketplaces and reselling them at a higher price on your ecommerce website. This requires careful research and scouting for profitable deals. Platforms like Amazon, eBay, and Walmart can be good sources for finding products to resell.

6. Local Artisans or Crafters: If you want to offer unique handmade or locally sourced products, you can collaborate with local artisans, crafters, or small businesses. Attend local craft fairs, reach out to local artists, or search on platforms like Etsy to find potential partners.

7. Private Labeling: Private labeling involves purchasing generic products from manufacturers and then branding them with your own label or logo. This allows you to sell unique products under your brand name. Alibaba, AliExpress, and Thomasnet can be helpful in finding private label suppliers.

Remember to consider factors like product quality, pricing, shipping times, and customer reviews when selecting products for your ecommerce website. Additionally, always ensure that the suppliers or manufacturers you choose are reliable and reputable.
