eBay has many people selling items. ebay as an organization does really know anything about the items for sale
. The vendors on ebay offer evrything and some vendors are more deceptive than others. Finding out the details of any purchace is always a good idea. You can post questions to any vendor and it's always a good thing to do first.
"Anchor Rode" is not all the same so you need to enquire about the details. You can generally find a lot of cheap
deals for 1/2 inch rode even in local discount stores. It's fine for a small runabout power boat
but not much else. If they can't disclose the exact details that you can verify I would pass. Big name rope makers also make cheap
rope too in addition to the premium ropes you might be seeking.
