We're glad you're selling on eBay! We wanted to let you know that we limit the number of items (active + sold) sellers can list based on selling record and buyer satisfaction. This helps ensure our sellers have time to understand the selling process, and can deliver the level of customer service they need to succeed on eBay.
You haven't reached the limit for yet as you still have 10 items available to list. Once you have established a good track record with your buyers, the number of items you’re allowed to list will increase.
