CanadaRAM said:And the reason that they so generously do this is that the Merchant who sold you the bag of chips has to pay B of A $0.15 to $0.25 per debit transaction, regardless how small (plus their rental on the machine, and their monthly service fees). So B of A encourages you to use your card for dozens and hundreds of trivial purchases to line their pockets with service fees, at the expense of those businesses who are forced to take your card or risk losing your patronage. The merchant loses money on every bag of chips bought this way.
Yes, but even with that $0.15 transaction fee for retailers, unless what you're buying from the store is $0.85, $4.85, $29.85, etc, the bank will lose money by rounding up the majority of the time (ie: when something costs $x.01 to $x.84). They make money by getting more people to put their savings into their Bank of America account.
