Except the part about having a wider market for our goods.
they know they are the most powerful online auction game in town.
This is all of it. They know that no matter what the fees are, people are glad to pay to get their products in front of the world.
I have sold keyboards to Tasmania. Would that have happened through an ebay wannabe? I doubt it.
Cost of doing business.
Because people were gaming them by putting all the money into shipping instead of base price, they simply started charging final value fee on the total sale. Ebay would love for sellers to all do free shipping, and I would be glad to, since there is no financial incentive not to, but I often fear that it artificially makes my prices look higher, whether they actually are, or not.
"Estimated shipping costs" what is that? If I charge $16.85 to ship a keyboard that is what the buyer pays.
All the fees are taken from the seller, so if postage is $16.85 I really need to be charging about $19 to break even.
