This step is highly recommended, especially if you are expanding your retail placement. All retailers have unique requirements, processes, and procedures and you should always be knowledgeable before approaching each avenue. Some trial and error is to be expected; however, you should not be completely blind.
We recommend seeking retail experts that specialize in a particular field to consult with. If you are interested in Costco placement, VendorCo offers one-on-one consultation sessions. Visit: https://vendorco.com/consulting-info for more information.
