It is possible that your paycheck was a little short because you missed a day or two, due to a sick child at home or you might have experienced a temporary cut in hours, without notice. Those that have a short-term cash shortage can rest easier, if they take advantage of payday loan advances that are affordable and offer flexible repayment terms. While it used to be that cash advances needed to be repaid with your next paycheck, that isn't necessarily the case anymore. Many of the payday loan advances that are available today, offer repayment terms up to 30 days and some have renewal options.
