I don’t understand limiting SKUs unless there is some sort of extra bandwidth capacity associated. Is Amazon trying to limit the number of offers a seller can make? Maximizing thus band-width?
eBay and Amazon have been on the warpath for a while now. Siding out small timers and such. The people who built them are now anathema to them.
They may go to Hell.
I guess they're trying to spread the impact, but they'd probably be better off by just cutting loose a bunch of their redundant vendors, then increasing their selectivity on the ones they choose to affiliate with.
