Hi,
I got the news a few weeks ago that my company 
was going under, and through no fault of our 
own.  Just a couple of days ago, we made a deal 
that saved us.  But, during the time that I 
thought I was going to be unemployed by Sept 1st, 
and starring bankruptcy (at age 23) in the face 
in just two months, three cels I had wanted for 
over a year went up for auction.  One of them was 
a top wishlist cel, and the others were just 
awesome shots too.  But, I absolutely couldnt 
spend on them.  To add insult to injury, a few 
more big wishlist cels went up on a dealer's site 
just two days before I got the good news about my 
company not going under.  But alas, I have lost 
them as well.  Now, these werent #1 wishlist 
cels, so I am not totally 100% in your shoes 
right now.  I do know that taking care of  
yourself, and your family is way more important.  
If this cel is that important to you, try asking 
the seller if you can work something out with 
them.  Other than that, I dont know any quick 
ways to earn 600$....if I did, Id be doing it 
right now!  I still took a huge paycut this 
month, so Im not out of the woods  yet.  Best of 
luck to you, hope you find work soon!
