Personally, I think it should be heading over to Amazon HQ and asking how eBay can integrate into the fulfilment network better so that business sellers can fulfil eBay orders at the same cost as Amazon orders from their Amazon stock

The only way this would happen is if eBay gave Amazon a rocket ship load of cash.

I’ve said this on a couple of threads now. why would Amazon match fees for a MFN order with an FBA order? The whole point of them being higher is to make selling via Amazon the most appealing method!
