Unfortunately, they use a lot of double talk... They tell you clearly that it will be a single lump payment of $390, but they mumble in that is only if you call them at least 3 days before it's due and tell them to take the whole thing... Otherwise, they take the 90.00 finance charge every payday for the first 5 weeks, then take the finance charge PLUS 50.00 towards the principal, for a total of 140/payday.
Their interest is a bit over 700%, but is actually Legal. Their explanation of the workings is probably barely legal, but it needs to be made law that they explain it CLEARLY and PLAINLY and give you a written copy BEFORE approving the loan...
