My mother, now deceased, had Discover for many years, I've had them for 11 and they have always seemed very nice, but confusing to me how the charges appear online. Recently I get a calculator out and try every which way to make the figures jive and they don't. Wish it was more clear. Never have this problem with my CITI card online. Paying my current Discover balance and just trusting that their figures are accurate. (I know Discover wouldn't intentionally cheat me.) I don't notice anyone saying Discover's figures are wrong.
