Starting today, due to amazon offers page changes we won’t be able to differentiate prime suppliers as SBA or FBA in the repricing process.
Therefore, Amazon sales tax markup will be applied for Prime in general (SBA&FBA) or Non Prime items based on your global settings.
Please make sure to keep that change in mind and set your settings appropriately.
If you won't change your settings, the settings that will apply on our back-end will be the higher percentage that you set prior for SBA/FBA.
