When you first start off selling products on Ebay, you will have limits on the AMOUNT of items you can sell, along with the total VALUE of the items you can sell. The more you sell and prove to be a seller who has great customer service (i.e. sales, on-time shipping, replying to customer inquiries), the more Ebay will increase your selling limits. In the image, you can see that my company (as of today) is allowed to sell over 500,000 items A MONTH totaling no more than 9 million in value.
