I run a small website that makes use of the Google Translate API for some functionality. Use of that functionality is pretty low and so I get billed $0.04 or $0.06 every month. Unless Google has terrific rates on credit card charges (and they probably do, but certainly not that great), it's probably costing them more to bill me than they make. Maybe there aren't that many low paying accounts and so it's not worth the man hours to work around, but it's always struck me as strange when there are 2 easy solutions 1) not bill accounts where the amount is < credit card fees, or 2) always bill a minimum amount (e.g. $5) which gets stored as credit and slowly used up.
