With a loan of this sort, you can start repayment whenever you are ready. If you have the money within days, that would be ideal, however very unlikely.
With PayDay Loans, repayment only needs to occur within 35 days after the loan has been take. The longer the term, the more the interest will be- of course- but allowing for this period allows you to organize all your finances to best tackle the costs for the next month.
A great solution for unexpected costs, this allows you to take on small amounts of debt without drowning or getting overloaded by it.
