Pics, or both your new and old rims? Do you have the staggered setup?
By "3 of the rims were mildly bent", do you mean they're no longer perfectly rounded? If so, there may not be an outlet for them; since you likely can't sell them w/o 1st fixing the bent (or hiding the fact which I presume it's beneath you) and you won't likely get your repair $$ back should you choose to fix them since they won't sell for much.
