How will Checkout impact my third party selling tool?

Mister Lister and Seller's Assistant: Mister Lister and Seller's Assistant support Checkout. If you use one of these tools and have not downloaded the latest version, please do so by clicking on the following links (as appropriate): Mister Lister Seller's Assistant Checkout has been modified to allow sellers to choose whether or not to display the Checkout button. Mister Lister and Seller's Assistant will be updated to support this change, however, sellers can use their existing versions of these tools to list items with or without Checkout. To turn Checkout on or off, go to the My eBay Selling tab and select the "Update Checkout preferences" option. Other third party selling tools: We encourage you to contact your service provider to find out how your tool might be affected.  more
