These are the sort of high-interest loans they advertise on late night television. Personally, I wouldn't recommend them. But, if you find this is your only option, you should be informed before borrowing money through some sort of cash advance or title loan:
Shop Around for a Rate - Each lender has its own fees and policies, don't blindly sign a contract without seeing what other lenders are offering.
Research the Lenders - Search the internet for reviews of lenders you are considering. Read what others have to say about the company.
Don't Pay Up front for a Loan - It is illegal for a lender to request an up front payment for a loan in the United States and Canada (and maybe other countries).
