<< I'm paying my CC bill 3 days late, will that have any negative effect on anything, such as a late fee or something on my credit history? It's only 3 days late. My CC company is MBNA by the way. >>
you mean 3 days after the date printed on the bill? Expect a late fee. Anywhere from $10-$30.
BTW, that date on the bill is the date it must be in their hands, not the date you can mail it out on.
