Ebay International Shipping?

[Balticfox]

Does the Ebay International Shipping program benefit anyone but Ebay?

A certain seller is offering five card lots of "Ex/Ex Mint" Topps 1959 and 1960 Baseball cards for $10 per lot. Shipping though is $16.44 for a single lot with combined shipping offered. Since that sounded reasonable, I put 20 lots (which amounted to 100 cards) in my basket expecting to see a reasonable rate for shipping 100 cards. Well I did not. What I saw was shipping of $116.36 and a taunt that I'd "saved" $207.76. (The mathematics doesn't even work.) Well in my universe that's not classified as a "saving". I'd instead be agreeing to being gouged on shipping. So no deal.

Since very few sellers would have the audacity to gouge on shipping to that extent, the Ebay International Shipping program certainly doesn't benefit the buyer. Does it benefit the seller in some way? Does the seller get a piece of the action, i.e. shipping fee?

Or is this International Shipping program solely to Ebay's benefit? Did Ebay just decide to eliminate buyers' constant complaints concerning sellers charging unreasonable shipping fees by instead charging the unreasonable shipping fees at the Ebay level and therefore turning the negative feedback into its own revenue stream?
