I've got a company...But don't have it on me right now - I'll write again tomorrow when I have it.
Ordered 300 of the window clings and 300 of the magnets earlier this year for our PTO. The local company we use for school clothing merchandise told me straight out to use this online guy as she 'couldn't touch his price'. I think we're selling the magnet for $3 and the cling for $2. That said, we aren't using it as a fundraiser and honestly, I would think you need to have a REALLY huge school to make this a worthwhile fundraiser. We have 600 kids in our school and have sold MAYBE 50 - 100 so far...and we've 'made' maybe $1 - $2 per item (like I said, we aren't using it as a fundraiser but rather a school spirit type thing). Even if half the kids buy one...We'd make a whopping $500 - $600, unless we mark them up a bunch more...and honestly I don't think they'd sell if we were marking them up more.
I'll write in with the company name tomorrow. But I would rethink this as a worthwhile fundraiser if I was you.
