We have heard from a few users regarding this issue thus far, and after touching base with eBay they are also aware and working to get it corrected ASAP.
The issue is some items are showing that shipping costs are free during a search, but when you go IN to the item itself they show the correct shipping amounts instead.
Again eBay has acknowledged this issue and is working to correct it, apparently no further action is required on the sellers part to fix the items.
