Ducky,
Now that I'm reading their requirements again (fully awake and caffeinated), the part that didn't make sense actually makes perfect sense, or should I say that I understand it (NOT that it makes sense, except to "R").
So, not only does a seller pay a start-up fee, s(he) pays an annual fee based on sales -- the more sold, the lower the fee. Result? You bust your butt trying to supply them with tons of stuff to sell, so that the privilege of doing so doesn't cost AS MUCH as if you didn't meet their quota. And then a late fee besides? What a colossal racket!
There's no way a person can make money, unless you manage estate sales and skim off the goodies. They must have people doing some serious volume, or neither would be coming out ahead. Absolutely mind-blowing!
And, as our Hedgie would say, "snicker, chortle, guffaw", or some such thing. :-D
Speaking of Hedgie, what's happening? Yanny?
