Sesame Street party goods

Hi!

I'm throwing my son a Sesame Street themed first birthday party in 2 weeks.  I love the new Sesame Street themed first bday party goods (with Elmo, Cookie & Big Bird on them) at party city, but I think they're plates, etc are very overpriced.  They charge 6.50 for a pack of 18 plates.  I'm having almost 50 people and will need lots of plates, since people will use more than one each.  

Does anyone know where to get these plates cheaper?  I may just buy regular red disposable plates, but I would like to have everything coordinated.  I just don't want to spend that much!

Thanks
