I have had my listing taken down because of this. IF you are listing this item over and over and over again, i suggest you lower the shipping. What i do is just lower it a few dollars and see if the message still comes out. Also your item will get less visibility if you list and ignore this message
Example, your item is about to end (15mins left) and there's another item with 60mins left (with cheaper shipping). They will show that 60min item first and yours will be below. |
