Have you identified a great product which you would love to retail subject to the fact that you find the right place to order them in bulk at wholesale prices from? What you are looking for are wholesalers and this is something that you will have to work hard for. If you are new to the retail business then most wholesalers may not be willing to work with you as they would already have established clients to move their inventory without needing to have to look for new customers every time.
However, this is usually true with high street wholesalers who tend to have such a mindset. To improve your chances of finding a good wholesaler who would be willing to offer you help in terms of facilitating for you to buy wholesale products, you will have to look online.
Look for directories that specialize in listing wholesalers in your area as they tend to have their own ways of identifying all possible wholesalers in any given area. They will have done all the hard work for you, the only thing left would be for you to figure out which ones would indeed be perfect for you to partner with. Obviously some may not be appropriate for your needs whereas others may have excuses to not work with you.
