I need help finding party supplies!?

I need BLACK and WHITE zebra printed paper plates for a graduation. but I haven’t been able to find any anywhere! I did find some square ones, but they were five dollars for eight of them, which is pretty ridiculous I think. As you can imagine there will be alot of people at this graduation party, so I need some cheap zebra printed plates that are only black and white. They can have purple on them, because the theme of the party is zebra print and purple. If you know of any party supply stores, please post a link below! It would be awesome to have some help! Thanks very much!
