eBay, from a survey they asked me to participate in, seem to be pushing their own labels.
However, I still have the option to select AP small satchel/box when selecting postage (which eBay labels are a subset of). I use flat rate (as that's what they are), so that might make a difference. Prepaid satchels are also a subset.
I stopped using calculated when eBay decided not to update to current rates a few years ago.
Whenever postage goes up, I bulk edit relevant listings. Only takes a few minutes for 1500+ listings, so not a biggie to allow me to set the correct postage.
