For Buying Groups or Channel Partners that manage many separate customers or even provide the data feed to Vusion for their ESLs, there is a limit for 200 retail chains per user. This makes it difficult for the admins of those partners over 200 as they usually used a shared mailbox to manage their customers. They cannot separate these customers into separate stores as a workaround, as many of these retail chains have multiple stores under them. Using separate email addresses will begin to make things confusing as they grow larger.
