Final Value Fee component "Other" that I don't recognize

[hajbo]

I sold a book just recently and looked at the payment details, specifically the final value fee calculation. There is one I have not seen before, called "Other" for 28 cents. Everything else I am familiar with, what is this extra "Other" fee for? Hope you can decipher the image, Fee based on 77.10, item price of 65, shipping 5.38, sales tax 6.44, all fine, but then the mysterious "Other" for 0.28
