Jess,
I believe Cashcentral and CashnetUsa are licensed in MOST states, but not all.

Check this link out to find out whether they are really licensed or not. Your original contract with them will have the dba name. I defaulted with them, and they are accepting my money orders and the collection calls stop. I've only been able to send them about $20 for right now because I'm catching up on my other bills and they will cash them. Send them the money orders via certified mail, and you can always offer to do small increments by prepaid debit card too, so you don't have to give them any new bank information.
They will tell you that they can't accept smaller amounts, but just be stubborn and send what you can afford because no matter what they say, they still will take the money, even if it's $10! I've been in default with one since January and another since March, and they haven't sent me to any outside collections agency (I believe Cashcentral does its own in-house collections anyway).
You will have to make arrangements with the storefronts since they are licensed and can take legal action
