PayPal has a "merchant rate" which is basically lower fees if you are selling more than $3000 per month. But they don't put you onto it automatically when you go through that threshold, you have to apply for it!

If you have sales of more than $3000, fo yourself a favour and apply for the merchant rate - it'll reduce your fees without lifting a finger:
