WTB: nickelodeon cartoon dvds

Hey all;

I'm looking to buy (cheap) dvd's for my daughter (I've been scouring craigslist to no avail and don't have the time to go to garage sales on the weekends).  She likes: spongebob, dora, diego, blue's clues, team umizoomi (etc.).  If anyone has any they are wanting to get rid of, please let me know!

Thanks!

Stacie
