Deli cups?

[Imabur.]

The grocery store I work at has them. I'm in CT though.

Of course if you're going to order them online, I could always try to get a bunch and send them to you =P. (Free)
P.S. - the ones I have are clear, it looks like the ones in the link are white, I don't know if that matters.

not sure of any stores, maybe a craft store? HOBO...?

these don't look to be pre-punched.

Not sure if what you were looking for

Nice quad post lol
