Why are my bins skipping numbers?

A skipped bin number doesn't mean a sale is lost. Every sale is still in your feed and on your manifest. Here's what causes a gap:

• A win that didn't go through. If a bin label already printed for it, that number isn't reused.
• Box capacity. With Box capacity on, a buyer whose box is full rolls into an extra box, labeled 4-2, 4-3 and so on.
• Weekly bundled shipping. A buyer on weekly bundling keeps their bin from an earlier show, so that number is still taken.

Not the same thing: giveaway-only winners and Buy It Now sales never take a bin, so they don't make gaps. See Giveaways and Buy It Now.
