When syndicating items to your retailers, it is important to bear in mind that we have to respect their rules regarding syndication rates and not all retailers can or want to receive the same quantity of items from vendors at any given time.

Typically we recommend that users submit items in batches of 100 items.
Walmart also limits the number of batches per hour to 5/hour.

We are continually working with retailers to increase these limits and improve syndication flow.
