Was at the open event yesterday and asked about Simple Delivery, with regards to combining shipping only 5% of orders have this so eBay just thought meh wont be a big issue, obviously its a 5% big issue and they are working on a solution to it.

To an extent - you can see their logic there. Many businesses adopt an 80/20 rule and a lot of business once you reach a critical mass, do adopt thought processes like that.

That being said, it sounds like they were very honest in their responses!
