I almost want to cancel my card I haven't even recieved yet just cause they're located in Sioux Falls, SD.... If anyone has ever dealt with First Premier grrrr..... you get sick of reading about Souix falls , SD -_-;
I believe it has something to do with interest rate caps in South Dakota. I went on one of those instant cash sites to see how much interest it was. In some states is was really low, like 6 or 8 and in South Dakota it was like 45 or something like that. That may be the same reason Chase is in Delaware, even though they have no branches in Delaware.
Sothu Dakota does not have corporate income tax, making it very friendly for numerous companies.
