Where can I buy a bunch of roses for cheap?

I go to a Preforming Arts school and there’s 4 other boys in our freshman class. We wanted to get roses for every girl in our grade (around 67) for Valentine’s Day. Where can I get a bunch of roses in bulk for a decent price?

Take some from your neighbor's yard.

sorry roses aren't cheap. you put the thought into it, now you have to pay up too. and you better know the exact number of girls or get extra, because if you leave a girl out you will look like a douche.

They cost less if you get them at the grocery store. At a flower shop or florist you pay much more.
