Flyertalkers--
If you hadn't considered making a loan before, now is the time! You can lend money using your points/miles-earning credit card and then as the loan is paid back, you have have the funds returned to your PayPal account.
You can make loans as small as $25 or over $1000. The loans are paid back in monthly installments over the period of the loan, which is usually around 8-14 months. Although there is a small risk, I have been lending for 2 years and have a 0% default rate on my loans. Each month you can have the funds returned to you, and then use your credit card to make more loans.
As one member pointed out, this is a lot easier than carrying coins to the bank! Earn miles while helping entrepreneurs in developing countries--what could be better?
