Finding suppliers is super essential for eBay sellers because there are too many suppliers out there, and you need to know the fundamentals to be able to pick out the right supplier.
There are 3 types of suppliers:
Trading company: Focus on some specialized categories;
Wholesale company: Pretty much sells anything;
Manufacturer: More customized option.
The final decision lies with you, depending on your products and your needs. If you’re new to online selling, go with wholesalers, which can lower prices for a few goods. A manufacturer is the best if you need more handmade items with a large number. Alibaba is a recommended place to find whatever kind of seller you want to sell.
