FBA Fulfillment Fees Largely Inaccurate


I noticed a lot of our items had their FBA fulfillment fees raised by more than 20%. We’re in the process of finding out the date they were increased.

For example this item:

Package dimensions: 7.0079 X 7.2835 X 12.9134 inches
Unit weight: 1.4859 pounds
FF: $6.18

By my calculations this should be $4.90, no? $6.18 is the price for an over 4 lb item.

This is occurring for over 100 ASINs.

I am curious if other sellers have encountered the same issue?
