I stopped selling on ebay last april, when they started to charge a FVF on shipping costs as well as item price...
so, if you are refering to the 10c listing fee being waived, that is "irrelevant" to most sellers...and certainly not relevant to a buyer
if you are saying that ebay is now waving all FVF's (making it "free" to sell), then I for one would start selling again, and would think that would be great for sellers...once again, not really relevant to a buyer, they still pay the same, but if more sellers like me, that stopped selling start again, gives more items , so good for buyer too
so, I need more info on your inquiry?
