@Judy: ebay is a publicly traded company, and, in my mind, they are all about the money. Charging a percentage of the shipping fees is a rather recent (within the last 2 years) development, and an attempt to stop sellers from gouging customers on shipping while keeping their items priced competitively.
But they have had a shipping calculator forever.
Now I don't know how expensive such a calculator would be for etsy to introduce, and I don't want something for nothing, but my main point was that the shipping profiles don't really do their job, if any change still needs to be applied manually. We have postal increases pretty much every year. This is very poorly designed, and I have to believe etsy gets inundated with pleas to fix this one way or another, but we are not hearing about it. If a shipping calculator is too expensive for the current fee structure, why don't they tell us, and give us an option to weigh in?
To me, this seems more important than coming up with new 'browse features' and whatnot. (I just realize, I may be a tad cranky, anticipating all that extra work coming up...)
