Online shelf space is practically infinite, but if you want to sell your products in Costco stores, you’ll have a lot more competition. To prove yourself as a vendor worthy of being stocked on physical shelves, you’ll have to prove to Costco that your product will be successful and competitive.
Remember that, due to the bulk nature of in-store Costco purchases, you’ll be required to provide a much higher stock volume than other stores. Make sure that your company will be able to process this. Determine the discount you'll give – and the new price point.
