We have "Movie Day" once each quarter, right about the time the teachers are needing a bit of extra time to do report cards.
We don't use it as a fundraiser, but you could if you wanted to. We rent two age appropriate movies, one for grades 1-3 and one for grades 4-6 (for instance grades 1-3 could see Walt Disney's Cinderella and grades 3-6 could see the Julie Andrews one, Princess Diary's ((or whatever that was called)), which was Cinderella for older kids). We send a note home telling the parents to send water bottles with the kids and the school (either Student Council or PTVO) provides a bag of popcorn for each student. You could charge for the popcorn, but we don't. It is supposed to, for us anyway, be a treat for the whole student body while providing the teachers with some 'down' time to do report cards. The event costs are minimal, the cost of renting a movie, popcorn, oil and bags (which you purchase in bulk at Smart and Final (10% discount) or Sams Club (we don't have one) or where ever...). It is a very inexpensive way to really treat your entire school...lol...

This is a big hit with the kids.
For Red Ribbon, I did something a bit different. We didn't do the ribbons, we did the tin pin-on buttons. Each student was told to hang on to the button for 'Surprise Drug Free Days' later in the year. I used donated prizes (I got them from the treasure chest of cheap stuff that our Santa Shop provided. They suggested selling the stuff for a dime, but I saw an opportunity for a free, year long drug free program). About every 6 weeks or so, the Asst. Principal and I declared a "Drug Free Day" and went classroom to classroom. Every student who had their pin got a free prize out of the box. If they had lost their pin, they got a new pin.

This was a big hit with the kids, especially the ones who hung on to their original pin all year. It warmed my heart each time a student passed me in the hall and held up their pin for me to see. The pins, by the way, said "I Believe In Me Drug Free". They never realized than each day they looked at the pin, that they were planting their own seeds of being drug free in the future.
