You will not be able to undo all of what you have done to damage your own credit if your credit history is in a shambles. You will hardly make a dent in your financial woes by simply worrying and waiting. There needs to be a concrete plan that you can do some real work on day by day. If that takes a little bit of help from someone else to get you there, including one of these types of payday loans, then you can certainly agree that such a loan offer makes sense.
To prevent usury (unreasonable and excessive rates of interest), some jurisdictions limit the annual percentage rate (APR) that any lender, including payday lenders, can charge. Some jurisdictions outlaw payday lending entirely, and some have very few restrictions on payday lenders. In the United States, the rates of these loans were formerly restricted in most states by the Uniform Small Loan Laws (USLL), with 36%-40% APR generally the norm.
