Hi J Dano,
Your eBay listings won't be effected by our webstore. The only change that will take place is if you added our banner to your listings, but that will be removed if you decide to cancel.
Keep in mind that Webstore won't change the design of your eBay store, but creates a storefront outside of eBay for your eBay listings. If you're interested in changing your eBay store design check out our eBay Store Designer solution.
Feel free to comment here if you have any other questions.
Best,
- Tzipi.
