Yes there was a lot of discussion on this over the last couple of week. Just use the search bar to find them or ask if you need to know anything specific.
This morning whilst generating labels I went through these post which you mentioned to get an idea but couldn’t find anything so was thinking to ask, I got this first “ Amazon optimized shipments” with zero placement fee option as well but I wasn’t sure so I clicked on “partial shipment splits” and paid $75 for two shipments. Would it make any difference if I click on the first option to avoid the placement fee?
Is your ship from wrong? There is usually an Amazon warehouse address displayed in the first box, and there is no fee.
Or are you choosing a service partnered with Amazon?
