Sorry I didn't give more details on my situation. I do appreciate the advice that you, specifically, gave to me. The checks had a stop payment placed on them, which did stop all acrual of interest. Unfortuantely one of the places decided to turn me over to the police, who took it to the prosecutor's office and received authorization to go forward with prosecution. I think they were trying to make an example of me. Let's not kid ourselves about who owns these places.
Anyway, I tried to do my own homework, but obviously it wasn't enough. It seems ridiculous to put someone in jail for up to a year for less than $200. I was able to pay the check off and prevent the prosecutor from pressing charges.
The other businesses agreed to work out payment arrangments, without any more interest. So, the advice to stop payment was actually good overall. It was just this one place who wanted to make a point; she said it was their "policy". So basically my point is simply BEWARE. I would advise that no one EVER do payday loans. You are much better off to get a loan from a pawnbroker or just starve for a week.
I have read a lot of your posts, LadyinRed, and you are very nonjudgemental and helpful to those of us who need your help and advice. So, once again, thank you!
