Many of us in our lifetime have gone through re-establishing our credit for one reason or another. To do this I do not recommend companies like these because they only want your money. They glean in the same limelight as pawnshops and payday loans, and take advantage of the less fortunate. I recommend the next time you have extra cash, say a tax refund, or sell something, put the money in the bank and apply for a secured credit card. Most institutions will do this. Do this in person and discus your options, and payment schedule. As for your payment due date what is written on your monthly statement is when it should be paid. Pay early and pay more than your minimum or pay it off each month. After a year you will have more offers for credit than your shredder can handle.

From their website this statement alone would make me turn around and go away.
The Continental Finance MasterCard is an unsecured credit card and is specifically designed for people who have had difficulties being approved for a major credit card because of a less than perfect credit history, including prior bankruptcy. This is a fee based product in which fees will be billed to your first statement, thus reducing your available credit until they are paid.
