Paypal hit me with a 9% fee ?

I am a seller on Bricklink with a small number of sales - one a month or so and have used paypal for payment. I have always in the past received a message from paypal with a subject like " , and the body just provides the amount and any note. When looking at my paypal account there is (as expected) a deduction of around 3.4% from the payment. This week I sold a small item on Bricklink and got a different email from paypal with a subject line "You've got money" and a different content - but this time it shows a transaction fee in the email - and it a was 9.1% fee. Wow - on their fee information paypal say it is 0-2500 (or something) at 3.4%. Why did I get such a big fee this time, was the money sent differently by the buyer ? Thanks , and sorry for being a beginner here - never seen this before over several years.
