Good advice on this post - PDL's are a major trap. My dad fell into that trap - he got one and thought he could pay it back I'm sure. But he couldn't and had to get another to pay that one and so on. When he passed away, my mom's paycheck went in the bank like 3 days later - she went to make a withdrawl only to find it at a negative balance b/c he owed so much -- he had more that 15 loans. It was a mess to say the least.
I know $70 is not a lot for a family of 6, especially in CA. Keep in mind like others have suggessted, you can talk to your utilites see if they will let you delay all or part of your payments for the 2 weeks to free up some more money. Can you carpool to save on gas? Or reduce how much you go out at all - I know work is a must, but for other things try to avoid it, or use public transportation.
For food, like other said - noodles are cheap, look for things like that & coupons. Lots of food banks and churches or other ogranizations can help out with food for 2 weeks.
Do you have anything you can sell for some extra $ quickly - or is there neighboors who may need their lawn mowed where you can make some extra cash fast? Even donating plasma - I think that pays around $35 or so... their are other options out there.
I would strongly encourage you to look at everything else possible than to get a PDL -- if you can just hang on for 2 weeks like you said, you will be okay. If you get the PDL you are most likley getting into an ugly trap that is impossible to escape from and will just create worse money problems.
Best of luck with whatever you decide.
