Hi Tammy,
If you’re listing as Fixed Price, eBay treats them as GTC. They will only end when they sell or your manually end them. If you use our Custom Duration, you can specify 30 days and they won’t relist unless you’re using Allocations Plans in the Enterprise Edition. If you having running listings you want to switch to a Custom Duration, you can select them in the Check Listings grid, right click and choose Set eBay Custom Duration to make sure they end in 30 days.
