I have terrible credit. I messed things up with I was younger and am currently rebuilding.
I was instantly approved for $300.00 with Paypal Connect with a 616 CK score.
Few things of note:
1) It will default to paypal connect as your primary funding source, so make sure you keep up with your due dates and usage.
2) I've read they do not send statements, it requires you to be diligent with your due dates
3) You do not receive a physical card. It's attached to your paypal account as another funding source
4) High interest, really only use once in a while to keep active and make sure you only put what you can pay back on the actual balance.
