Pulling out of a retailer may be due to a myriad reasons. This can be from changing your branding and then your brand might not fit the retailer’s customers. Another reason one might pull out of a retailer would be the payment methods. Some retailers offer consignment while other retailers give you net 30 days. Depending on the situation, you need to analyze it. I kindly let the retailer know in advance that I cannot work with them anymore due to the specific reasons.
