I don't know anything about business accounts, but personal accounts do accrue fees now. They didn't used to but they have changed all that. I used to have a personal account and a premiere account and would ask people (not ebay but other sales) to send to my personal if they were using bank/existing funds and to my premiere (with fees no matter what the transaction) for credit cards.
Do you have to have a certain amount of activity with a business account? Also the issue is not fees for printing postage but fees for receiving payments.
